Struct WitnessHash 

pub struct WitnessHash { /* private fields */ }

A 256-bit witness commitment hash.

Used to anchor state transitions in the RVM witness trail. This is a fixed-size value type suitable for embedding in no_std contexts without heap allocation.

Implementations

impl WitnessHash

pub const ZERO: Self

The zero hash, used as a sentinel for the genesis state.

pub const fn from_bytes(bytes: [u8; 32]) -> Self

Create a witness hash from raw bytes.

pub const fn as_bytes(&self) -> &[u8; 32]

Return the raw byte representation.

pub const fn is_zero(&self) -> bool

Check whether this is the zero (genesis) hash.
