Struct exocore_core::framing::sized::SizedFrame

pub struct SizedFrame<I: FrameReader> { /* private fields */ }

Frame that encode the size of the underlying frame so that it can expose the exact data when decoding. The size is prepended and appended to support to support iteration in both directions.

Implementations

impl<I: FrameReader> SizedFrame<I>

pub fn new(inner: I) -> Result<SizedFrame<I>, Error>

pub fn new_from_next_offset( inner: I, next_offset: usize ) -> Result<SizedFrame<I>, Error>

pub fn size(&self) -> usize

impl SizedFrame<Bytes>

pub fn new_from_reader<R: Read>( reader: &mut R ) -> Result<SizedFrame<Bytes>, Error>

Trait Implementations

impl<I: FrameReader + Clone> Clone for SizedFrame<I>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<I: FrameReader> FrameReader for SizedFrame<I>

type OwnedType = SizedFrame<Bytes>

fn exposed_data(&self) -> &[u8]

Data exposed by this frame to inner frame. Ex: sized frame will expose the sized data without encoded size numbers

fn whole_data(&self) -> &[u8]

Data of the whole frame, not just the exposed data.

fn to_owned_frame(&self) -> Self::OwnedType

Converts the frame to a owned version (without lifetime)

fn whole_data_size(&self) -> usize

Size of the whole data of the frame.

fn copy_to<W: Write>(&self, writer: &mut W) -> Result<(), Error>

Copy the frame into the given writer

fn copy_into(&self, into: &mut [u8]) -> Result<usize, Error>

Copy the frame into the given slice
