--- failure auto_trait_impl_removed: auto trait no longer implemented ---

Description:
A public type has stopped implementing one or more auto traits. This can break downstream code that depends on the traits being implemented.
        ref: https://doc.rust-lang.org/reference/special-types-and-traits.html#auto-traits
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.48.0/src/lints/auto_trait_impl_removed.ron

--- failure trait_method_missing: pub trait method removed or renamed ---

Description:
A trait method is no longer callable, and may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#trait-item-signature
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.48.0/src/lints/trait_method_missing.ron

--- failure trait_method_now_returns_unit: pub trait method now returns unit ---

Description:
A trait method that used to return a value now returns `()`.

--- failure trait_method_parameter_count_changed: pub trait method parameter count changed ---

Description:
A trait method now takes a different number of parameters.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#trait-item-signature
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.48.0/src/lints/trait_method_parameter_count_changed.ron

--- 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.

Changelog

differential-dataflow

0.26.0 - 2026-07-29

Other

• int_proxy join: draw the proxy collection lazily, a block at a time (#809)

differential-dogs3

0.25.0 - 2026-07-15

Changed

• Track differential-dataflow 0.25: layout moves onto the Cursor and navigation becomes an optional capability. (#772)

Fixed

• lookup_map: correct an off-by-one in key-container indexing (index(1) -> index(0)). (#765)
