Trait Implementations

impl Reader<u16, U16be> for U8Reader<'_>

fn next(&mut self) -> Result<U16be, ReadError>

fn next_n(&mut self, buf: &mut [U16be]) -> Result<(), ReadError>

read buf-many items from this reader in bulk. if Reader cannot read buf-many items, return ReadError::ExhaustedInput.

fn mark(&mut self)

mark the current position as where to measure offset against.

fn offset(&mut self) -> u16

the difference, in Address, between the current Reader position and its last mark. when created, a Reader’s initial position is marked, so creating a Reader and immediately calling offset() must return Address::zero().

fn total_offset(&mut self) -> u16

the difference, in Address, between the current Reader position and the initial offset when constructed.
