pub trait DiffFormat<S, B>: Format<S, B> { }Expand description
Public, nameable bound for a diff format, either changeset or patchset.
This is the downstream-visible counterpart to the crate-private
Format trait. It carries no items of its own; the associated types
live on the sealed supertrait and stay private. Because Format is
crate-private, no external type can satisfy this bound, so it is sealed
in the same sense as a sealed trait: only ChangesetFormat and
PatchsetFormat implement it.
A consumer that only calls new, digest, and build can therefore
write one function generic over F: DiffFormat<String, Vec<u8>> and
fold a batch of wire events into either a changeset or a patchset,
instead of duplicating the body once per format.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
