Trait HashAxis 

pub trait HashAxis: AxisExtension {
    const AXIS_ADDRESS: &'static str = "https://uor.foundation/axis/HashAxis";
    const MAX_OUTPUT_BYTES: usize = 64;

    // Required method
    fn hash(input: &[u8], out: &mut [u8]) -> Result<usize, ShapeViolation>;
}

Wiki ADR-031 canonical hash-function family.

Single kernel hash(input: &[u8], out: &mut [u8]) emitting the digest of input into the first Self::MAX_OUTPUT_BYTES of out. Per ADR-030’s signature constraint every axis-kernel method takes (input: &[u8], out: &mut [u8]) -> Result<usize, ShapeViolation>; HashAxis exposes only one kernel because per-impl (Sha256Hasher / Sha512Hasher / Sha3_256Hasher / Keccak256Hasher / Blake3Hasher) the axis position in the model’s AxisTuple already commits to a single digest family.

Provided Associated Constants

const AXIS_ADDRESS: &'static str = "https://uor.foundation/axis/HashAxis"

const MAX_OUTPUT_BYTES: usize = 64

Required Methods

fn hash(input: &[u8], out: &mut [u8]) -> Result<usize, ShapeViolation>

Compute the digest of input into out[..n], returning n.

Errors

Returns ShapeViolation if out is too small to hold the digest.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
