Trait packet::ParseBufferMut

pub trait ParseBufferMut: ParseBuffer + ContiguousBufferMut {
    // Required method
    fn parse_with_mut<'a, ParseArgs, P: ParsablePacket<&'a mut [u8], ParseArgs>>(
        &'a mut self,
        args: ParseArgs
    ) -> Result<P, P::Error>;

    // Provided method
    fn parse_mut<'a, P: ParsablePacket<&'a mut [u8], ()>>(
        &'a mut self
    ) -> Result<P, P::Error> { ... }
}

A ParseBuffer which provides mutable access to its contents.

While a ParseBuffer allows the ranges covered by its prefix, body, and suffix to be modified, it only provides immutable access to their contents. A ParseBufferMut, on the other hand, provides mutable access to the contents of its prefix, body, and suffix.

Notable implementations

ParseBufferMut is implemented for mutable byte slices - &mut [u8]. Mutable byte slices do not implement GrowBuffer or GrowBufferMut; once bytes are consumed from their bodies, those bytes are discarded and cannot be recovered.

Required Methods

fn parse_with_mut<'a, ParseArgs, P: ParsablePacket<&'a mut [u8], ParseArgs>>( &'a mut self, args: ParseArgs ) -> Result<P, P::Error>

Parses a mutable packet with arguments.

parse_with_mut is like parse_mut, but it accepts arguments to pass to P::parse_mut.

Provided Methods

fn parse_mut<'a, P: ParsablePacket<&'a mut [u8], ()>>( &'a mut self ) -> Result<P, P::Error>

Parses a mutable packet from the body.

parse_mut is like ParseBuffer::parse, but instead of calling P::parse on a BufferView, it calls P::parse_mut on a BufferViewMut. The effect is that the parsed packet can contain mutable references to the buffer. This can be useful if you want to modify parsed packets in-place.

Depending on the implementation of P::parse_mut, the contents of the buffer may be modified during parsing.

See the BufferViewMut and ParsablePacket documentation for more details.
