Trait CanonicalWrite 

pub trait CanonicalWrite {
    // Required method
    fn canonical_write(&self, out: &mut StateHasher);
}

Values with one frozen canonical byte representation.

An implementation must be self-delimiting: the shape of its writes (which primitive writes, in what order) may depend only on values it has already written. Write a length (with StateHasher::bytes, StateHasher::sequence or StateHasher::length) before variable-length data, and a tag before an optional value or enum variant. Otherwise distinct values encode alike: if Slot(Option<u32>) writes its u32 only when Some, sequence(&[Slot(None), Slot(Some(5))]) and sequence(&[Slot(Some(5)), Slot(None)]) hash the same.

Required Methods

fn canonical_write(&self, out: &mut StateHasher)

Writes this value using its documented canonical byte representation.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
