🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
If there are types that satisfy both impls, invokes on_overlap
with a suitably-freshened ImplHeader
with those types
substituted. Otherwise, invokes no_overlap
.
