Summary by CodeRabbit

  • Documentation
    • Updated example code in the documentation to explicitly handle potential errors when hashing actions, providing clearer error messages if hashing fails.

Walkthrough

Update the example in the documentation of src/hasher.rs to explicitly handle the Result returned by ActionHasher::hash(&action) using .expect("failed to hash action"). No changes are made to the actual code logic or public API, only to the documentation example.

Changes

Cohort / File(s) Change Summary
Documentation Example Update
src/hasher.rs
Modify the example to handle the Result from ActionHasher::hash(&action) with .expect("failed to hash action").

Poem

A docstring’s tale, now more robust,
With .expect it earns our trust.
No silent fails, no cryptic dread,
"Hash action" shouts if things go dead.
A tiny tweak, a safer guide—
Let documentation be our pride!

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Explain this complex logic.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai explain this code block.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and explain its main purpose.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Run this script to locate and label all remaining unlabelled fenced code blocks in Rust doc comments and Markdown files:

#!/bin/bash

echo "Rust doc comments without language tag:"
rg -n -P '^(//!|///)\s*```(?!\w)'

echo
echo "Markdown files without language tag on code fences:"
rg -n '^```$' --glob '*.md'

Label each occurrence with the appropriate language (e.g. ```````rust``) to satisfy MD040 and prevent doctest warnings.

**/*.rs

📄 CodeRabbit Inference Engine (AGENTS.md)

**/*.rs: Clippy warnings MUST be disallowed.
Fix any warnings emitted during tests in the code itself rather than silencing them.
Where a function is too long, extract meaningfully named helper functions adhering to separation of concerns and CQRS.
Where a function has too many parameters, group related parameters in meaningfully named structs.
Where a function is returning a large error consider using Arc to reduce the amount of data returned.
Write unit and behavioural tests for new functionality. Run both before and after making any change.
Every module must begin with a module level (//!) comment explaining the module's purpose and utility.
Document public APIs using Rustdoc comments (///) so documentation can be generated with cargo doc.
Prefer immutable data and avoid unnecessary mut bindings.
Handle errors with the Result type instead of panicking where feasible.
Avoid unsafe code unless absolutely necessary and document any usage clearly.
Place function attributes after doc comments.
Do not use return in single-line functions.
Use predicate functions for conditional criteria with more than two branches.
Lints must not be silenced except as a last resort.
Lint rule suppressions must be tightly scoped and include a clear reason.
Prefer expect over allow.
Prefer .expect() over .unwrap().
Use concat!() to combine long string literals rather than escaping newlines with a backslash.
Prefer semantic error enums: Derive std::error::Error (via the thiserror crate) for any condition the caller might inspect, retry, or map to an HTTP status.
Use an opaque error only at the app boundary: Use eyre::Report for human-readable logs; these should not be exposed in public APIs.
Never export the opaque type from a library: Convert to domain enums at API boundaries, and to eyre only in the main main() entrypoint or top-level async task.
