Struct SubgroupObjectReader 

pub struct SubgroupObjectReader { /* private fields */ }

Implementations

impl SubgroupObjectReader

pub fn new(header: &SubgroupHeader) -> Self

pub fn read_object( &mut self, buf: &mut impl Buf, ) -> Result<SubgroupObject, CodecError>

pub fn read_object_meta( &mut self, buf: &mut impl Buf, ) -> Result<SubgroupObjectMeta, CodecError>

Decode the next object’s framing without copying its payload.

Consumes exactly the bytes Self::read_object consumes and leaves the same delta state behind, so the two are interchangeable on a given stream.

pub fn write_object( &mut self, object: &SubgroupObject, buf: &mut impl BufMut, ) -> Result<(), CodecError>

Serialize an object, producing the correct delta encoding.

A zero payload_length writes the object’s status, defaulting to ObjectStatus::Normal when it is None. The status is typed, so every value that can reach this method is one draft-18 assigns and one Self::read_object accepts; there is no status-related error to return.

Errors with CodecError::InvalidField when object.object_id is not strictly greater than the previously written object’s ID, since no valid delta exists for that case.

Errors with CodecError::InvalidField when payload_length is not exactly payload.len(). The declared length is written ahead of the payload, so a mismatch is a frame Self::read_object cannot parse and one no caller could fix by appending bytes.
