Struct NodeAsKey

Source
#[repr(transparent)]
pub struct NodeAsKey<T>(pub T) where T: Deref + ?Sized;
Expand description

Wrapper for pointer types that implements by-address comparison.

See the crate-level documentation for details.

Equality tests and hashes on fat pointers (&dyn Trait, &[T], &str, etc) include the attribute of the fat pointer.

However, note that comparing fat pointers to trait objects can be unreliable because of Rust issue #46139. In some cases, ByThinAddress may be more useful.
