Struct StreamVerifier 

pub struct StreamVerifier<'a> { /* private fields */ }

A StreamVerifier to verify a signature against a data stream

This mode of operation allows for verification of large files by processing them in chunks, without having to load the entire file into memory.

Note that this mode only works with pre-hashed signatures (not legacy mode).

Implementations

impl StreamVerifier<'_>

pub fn update(&mut self, buf: &[u8])

Update the verifier with a chunk of data

This method can be called multiple times with different chunks of the file to be verified. The chunks will be hashed incrementally.

pub fn finalize(&mut self) -> Result<(), Error>

Finalize the verification process

This method must be called after all data has been processed with update(). It computes the final hash and verifies the signature.

Returns Ok(()) if the signature is valid, or an error otherwise.

Trait Implementations

impl<'a> Clone for StreamVerifier<'a>

fn clone(&self) -> StreamVerifier<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
