Struct Reader 

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

In-memory reader that allows direct reads from the source buffer into user given destination buffers.

Implementations

impl<'a> Reader<'a>

pub fn new(bytes: &'a [u8]) -> Self

pub fn peek(&self) -> ReadResult<&u8>

pub fn read_exact(&mut self, dst: &mut [MaybeUninit<u8>]) -> ReadResult<()>

Copy exactly dst.len() bytes from the Reader into dst.

pub unsafe fn read_t<T>(&mut self, dst: &mut MaybeUninit<T>) -> ReadResult<()>

Copy exactly size_of::<T>() bytes from the Reader into dst.

Safety

• T must be initialized by reads of size_of::<T>() bytes.

pub unsafe fn read_slice_t<T>( &mut self, dst: &mut [MaybeUninit<T>], ) -> ReadResult<()>

Copy exactly dst.len() * size_of::<T>() bytes from the Reader into dst.

Safety

• T must be initialized by reads of size_of::<T>() bytes.

pub fn read_borrowed(&mut self, len: usize) -> ReadResult<&'a [u8]>

Read exactly len bytes from the cursor into a slice.

pub unsafe fn get_t<T>(&mut self) -> ReadResult<T>

Read T from the cursor into a new T.

Safety

• T must be initialized by reads of size_of::<T>() bytes.

pub fn as_slice(&self) -> &[u8]

pub fn consume_unchecked(&mut self, amt: usize)

Advance the cursor by amt bytes without checking bounds.

pub fn consume(&mut self, amt: usize) -> ReadResult<()>

Advance amt bytes from the reader and discard them.
