Trait digest::XofReader [−][src]
pub trait XofReader {
fn read(&mut self, buffer: &mut [u8]);
fn read_boxed(&mut self, n: usize) -> Box<[u8]> { ... }
}Trait for describing readers which are used to extract extendable output from XOF (extendable-output function) result.
Required methods
fn read(&mut self, buffer: &mut [u8])[src]
Read output into the buffer. Can be called an unlimited number of times.
Provided methods
fn read_boxed(&mut self, n: usize) -> Box<[u8]>[src]
Read output into a boxed slice of the specified size.
Can be called an unlimited number of times in combination with read.
Box<[u8]> is used instead of Vec<u8> to save stack space, since
they have size of 2 and 3 words respectively.
