Implementations§

source§

impl<'a> MemDecoder<'a>

source

pub fn new(data: &'a [u8], position: usize) -> MemDecoder<'a>

source

pub fn data(&self) -> &'a [u8]

source

pub fn len(&self) -> usize

source

pub fn remaining(&self) -> usize

source

fn decoder_exhausted() -> !

source

pub fn read_array<const N: usize>(&mut self) -> [u8; N]

source

pub fn with_position<F, T>(&mut self, pos: usize, func: F) -> T
where F: Fn(&mut MemDecoder<'a>) -> T,

While we could manually expose manipulation of the decoder position, all current users of that method would need to reset the position later, incurring the bounds check of set_position twice.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
