From 8ebc92ecef9ecf9577b02791dfe91c5503920c96 Mon Sep 17 00:00:00 2001 From: shua Date: Wed, 19 Nov 2025 13:49:23 +0100 Subject: [PATCH 1/8] Add allocator param to String This is a third attempt at implementing adding Allocator support to the std lib's `String`. Still stuck on the same issue with type inference failing on the newly generic `String`, but I opted to do even less than the previous WIP work, and have added no new functions (`String` can be constructed via `Vec` or `Box`), and have moved only the struct definition to its own mod to make rebasing a bit easier if/when main changes underneath me. --- library/alloc/src/boxed.rs | 12 +- library/alloc/src/str.rs | 18 +- library/alloc/src/string.rs | 419 ++++++++++++++++++++-------------- library/std/src/ffi/os_str.rs | 4 +- library/std/src/path.rs | 16 +- 5 files changed, 282 insertions(+), 187 deletions(-) diff --git a/library/alloc/src/boxed.rs b/library/alloc/src/boxed.rs index 2b767ffe02bee..8ebab73e788f1 100644 --- a/library/alloc/src/boxed.rs +++ b/library/alloc/src/boxed.rs @@ -211,6 +211,8 @@ use crate::alloc::{AllocError, Allocator, Global, Layout}; use crate::raw_vec::RawVec; #[cfg(not(no_global_oom_handling))] use crate::str::from_boxed_utf8_unchecked; +#[cfg(not(no_global_oom_handling))] +use crate::vec::Vec; /// Conversion related impls for `Box<_>` (`From`, `downcast`, etc) mod convert; @@ -1917,11 +1919,13 @@ impl Clone for Box<[T], A> { #[cfg(not(no_global_oom_handling))] #[stable(feature = "box_slice_clone", since = "1.3.0")] -impl Clone for Box { +impl Clone for Box { fn clone(&self) -> Self { - // this makes a copy of the data - let buf: Box<[u8]> = self.as_bytes().into(); - unsafe { from_boxed_utf8_unchecked(buf) } + let alloc = Box::allocator(self).clone(); + let len = self.len(); + let mut vec: Vec = Vec::with_capacity_in(len, alloc); + vec.extend_from_slice(self.as_bytes()); + unsafe { from_boxed_utf8_unchecked(vec.into_boxed_slice()) } } } diff --git a/library/alloc/src/str.rs b/library/alloc/src/str.rs index e772ac25a95c2..6e28ae3e42ce5 100644 --- a/library/alloc/src/str.rs +++ b/library/alloc/src/str.rs @@ -7,6 +7,7 @@ // It's cleaner to just turn off the unused_imports warning than to fix them. #![allow(unused_imports)] +use core::alloc::Allocator; use core::borrow::{Borrow, BorrowMut}; use core::iter::FusedIterator; use core::mem::MaybeUninit; @@ -52,7 +53,7 @@ use core::{mem, ptr}; use crate::borrow::ToOwned; use crate::boxed::Box; use crate::slice::{Concat, Join, SliceIndex}; -use crate::string::String; +use crate::string::generic::String; use crate::vec::Vec; /// Note: `str` in `Concat` is not meaningful here. @@ -186,7 +187,7 @@ where } #[stable(feature = "rust1", since = "1.0.0")] -impl Borrow for String { +impl Borrow for String { #[inline] fn borrow(&self) -> &str { &self[..] @@ -194,7 +195,7 @@ impl Borrow for String { } #[stable(feature = "string_borrow_mut", since = "1.36.0")] -impl BorrowMut for String { +impl BorrowMut for String { #[inline] fn borrow_mut(&mut self) -> &mut str { &mut self[..] @@ -234,7 +235,7 @@ impl str { #[stable(feature = "str_box_extras", since = "1.20.0")] #[must_use = "`self` will be dropped if the result is not used"] #[inline] - pub fn into_boxed_bytes(self: Box) -> Box<[u8]> { + pub fn into_boxed_bytes(self: Box) -> Box<[u8], A> { self.into() } @@ -497,8 +498,8 @@ impl str { #[rustc_allow_incoherent_impl] #[must_use = "`self` will be dropped if the result is not used"] #[inline] - pub fn into_string(self: Box) -> String { - let slice = Box::<[u8]>::from(self); + pub fn into_string(self: Box) -> String { + let slice = Box::<[u8], A>::from(self); unsafe { String::from_utf8_unchecked(slice.into_vec()) } } @@ -614,8 +615,9 @@ impl str { #[stable(feature = "str_box_extras", since = "1.20.0")] #[must_use] #[inline] -pub unsafe fn from_boxed_utf8_unchecked(v: Box<[u8]>) -> Box { - unsafe { Box::from_raw(Box::into_raw(v) as *mut str) } +pub unsafe fn from_boxed_utf8_unchecked(v: Box<[u8], A>) -> Box { + let (ptr, alloc) = Box::into_raw_with_allocator(v); + unsafe { Box::from_raw_in(ptr as *mut str, alloc) } } /// Converts leading ascii bytes in `s` by calling the `convert` function. diff --git a/library/alloc/src/string.rs b/library/alloc/src/string.rs index 4a2689e01ff17..3b35302ff4096 100644 --- a/library/alloc/src/string.rs +++ b/library/alloc/src/string.rs @@ -56,8 +56,7 @@ use core::ops::{self, Range, RangeBounds}; use core::str::pattern::{Pattern, Utf8Pattern}; use core::{fmt, hash, ptr, slice}; -#[cfg(not(no_global_oom_handling))] -use crate::alloc::Allocator; +use crate::alloc::{Allocator, Global}; #[cfg(not(no_global_oom_handling))] use crate::borrow::{Cow, ToOwned}; use crate::boxed::Box; @@ -67,6 +66,31 @@ use crate::str::{self, CharIndices, Chars, Utf8Error, from_utf8_unchecked_mut}; use crate::str::{FromStr, from_boxed_utf8_unchecked}; use crate::vec::{self, Vec}; +/// A hack because we cannot add a type parameter, even one with a default value, to existing types +/// which previously had no parameters. +/// +/// Introducing generic parameters means any use of the type is now a possible site of type +/// inference.

There's some lazy-loading that the browser does, but linkchecker doesn't, so maybe some general-purpose solution would be better, but this seemed better than a big list of exceptions. --- RELEASES.md | 48 +++++++++---------- library/alloc/src/string.rs | 2 +- library/core/src/any.rs | 2 +- library/core/src/borrow.rs | 4 +- library/core/src/char/methods.rs | 2 +- library/core/src/convert/mod.rs | 6 +-- library/core/src/iter/traits/iterator.rs | 2 +- library/core/src/marker.rs | 2 +- library/core/src/ops/deref.rs | 4 +- library/core/src/option.rs | 8 ++-- library/core/src/pin.rs | 2 +- library/core/src/primitive_docs.rs | 4 +- library/core/src/str/converts.rs | 2 +- library/core/src/str/error.rs | 2 +- library/core/src/str/lossy.rs | 2 +- library/core/src/str/mod.rs | 2 +- library/core/src/task/poll.rs | 2 +- library/std/src/panic.rs | 2 +- .../string-deref-patterns.md | 2 +- src/tools/linkchecker/main.rs | 19 ++++++++ .../crates/ide-db/src/generated/lints.rs | 2 +- tests/rustdoc-js-std/basic.js | 2 +- tests/rustdoc-js-std/from_u.js | 2 +- .../rustdoc-js-std/return-specific-literal.js | 4 +- tests/rustdoc-js-std/return-specific.js | 4 +- tests/rustdoc-js-std/string-from_ut.js | 10 ++-- .../intra-doc/empty-associated-items.stderr | 2 +- .../decl-trailing-whitespace.declaration.html | 8 ++-- tests/rustdoc/intra-doc/associated-items.rs | 2 +- tests/rustdoc/masked.rs | 6 +-- .../check-source-code-urls-to-def.rs | 2 +- 31 files changed, 91 insertions(+), 72 deletions(-) diff --git a/RELEASES.md b/RELEASES.md index b14cc499b46d0..6958501721e8c 100644 --- a/RELEASES.md +++ b/RELEASES.md @@ -98,8 +98,8 @@ Stabilized APIs -
