Trait CollisionResistance 

pub trait CollisionResistance {
    type CollisionResistance: Unsigned;
}

Types with a certain collision resistance.

Required Associated Types

type CollisionResistance: Unsigned

Collision resistance in bytes.

This applies to an output size of at least 2 * CollisionResistance bytes. For a smaller output size collision resistance can be usually calculated as min(CollisionResistance, OutputSize / 2).

Dyn Compatibility

This trait is dyn compatible.

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

impl CollisionResistance for lib_q_hash::CShake256

impl CollisionResistance for Kmac128

impl CollisionResistance for Kmac256

type CollisionResistance = UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>

impl CollisionResistance for Kt128<'_>

128-bit collision resistance per RFC 9861 §7.7, conditional on output length: this figure applies at an output of at least 2 * CollisionResistance = 32 bytes, per the digest::CollisionResistance trait contract. Kt128 is a XOF with no fixed output size, so that length is the caller’s choice: at a shorter output, the same contract gives min(CollisionResistance, OutputSize / 2) bytes.

type CollisionResistance = UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>

impl CollisionResistance for Kt256<'_>

256-bit collision resistance per RFC 9861 §7.8, conditional on output length: this figure applies at an output of at least 2 * CollisionResistance = 64 bytes, per the digest::CollisionResistance trait contract. Kt256 is a XOF with no fixed output size, so that length is the caller’s choice: at a shorter output, the same contract gives min(CollisionResistance, OutputSize / 2) bytes — e.g. 128-bit, not 256-bit, at the 32-byte output used in this crate’s examples.
