pub struct Digest(/* private fields */);
Expand description
Digest represents the results of a hashing function. It is always 256 bits of storage although depending on the hash it may have additional structure (for example Poseidon’s output is actually composed of field elements). The storage is in u32’s in part to simplify alignment requirements, especially in the zkVM.
Implementations§
source§impl Digest
impl Digest
sourcepub const fn from_bytes(bytes: [u8; 32]) -> Self
pub const fn from_bytes(bytes: [u8; 32]) -> Self
Construct a digest from a array of bytes in a const context.
Outside of const context, Digest::from
is recommended.
sourcepub fn as_mut_words(&mut self) -> &mut [u32]
pub fn as_mut_words(&mut self) -> &mut [u32]
Returns a mutable slice of words.
sourcepub fn as_mut_bytes(&mut self) -> &mut [u8] ⓘ
pub fn as_mut_bytes(&mut self) -> &mut [u8] ⓘ
Returns a mutable slice of bytes.
