Struct Prehash 

Source 
pub struct Prehash<'i, 'o, P, I> { /* private fields */ }
Expand description

A finalized prehash with independent short identity/output borrows.

Only common processing constructs this view from a completed state bound to the same resolved identity/provider. Byte width alone never establishes that provenance. There is no public arbitrary digest-plus-OID constructor.

Implementations§

Source§

impl<'i, 'o, P, I> Prehash<'i, 'o, P, I>

Source

pub fn from_provider(&self, provider: &P) -> bool

Whether the supplied instance actually completed this finalized input.

Source

pub fn identity(&self) -> &'i I

Full selected-provider algorithm identity, including parameters/defaults.

Source

pub fn as_bytes(&self) -> &'o [u8] ⓘ

Original finalized output bytes; accessing them performs no new hashing.
