Struct buffertk::LengthPrefixer

pub struct LengthPrefixer<'a, P>where
    P: Packable + 'a,{ /* private fields */ }

A type that packs a slice of objects by concatenating their packed representations. Prepends a length.

Trait Implementations

impl<'a, P> Packable for LengthPrefixer<'a, P>where P: Packable + 'a,

fn pack_sz(&self) -> usize

pack_sz returns the number of bytes required to serialize the Packable object.

fn pack(&self, out: &mut [u8])

pack fills in the buffer out with the packed binary representation of the Packable object. The implementor is responsible to ensure that out is exactly pack_sz() bytes and implementations are encouraged to assert this.

fn stream<W: Write>(&self, writer: &mut W) -> Result<usize, Error>where Self: Sized, for<'a> &'a Self: Packable,

stream writes the object to the provided writer using the same representation that would be used in a call to pack. The implementor is responsible for making sure that the number of bytes written is exactly equal to the number of required bytes.
