⚠ columnar breaking changes

--- failure constructible_struct_adds_field: externally-constructible struct adds field ---

Description:
A pub struct constructible with a struct literal has a new pub field. Existing struct literals must be updated to include the new field.
        ref: https://doc.rust-lang.org/reference/expressions/struct-expr.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.46.0/src/lints/constructible_struct_adds_field.ron

  field Bools.tail in /tmp/.tmp5Ad26r/columnar/src/primitive.rs:918

--- failure copy_impl_added: type now implements Copy ---

Description:
A public type now implements Copy, causing non-move closures to capture it by reference instead of moving it.

       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.46.0/src/lints/copy_impl_added.ron

--- failure trait_requires_more_generic_type_params: trait now requires more generic type parameters ---

Description:
A trait now requires more generic type parameters than it used to. Uses of this trait that supplied the previously-required number of generic types will be broken. To fix this, consider supplying default values for newly-added generic types.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#trait-new-parameter-no-default

--- failure type_allows_fewer_const_generic_params: type now allows fewer const generic parameters ---

Description:
A type now allows fewer const generic parameters than it used to. Uses of this type that supplied all previously-supported const generics will be broken.

--- failure type_mismatched_generic_lifetimes: type now takes a different number of generic lifetimes ---

Description:
A type now takes a different number of generic lifetime parameters. Uses of this type that name the previous number of parameters will be broken.
