Struct RenderDataWriter 

pub struct RenderDataWriter { /* private fields */ }

Appends the operations of a render data stream to a byte buffer.

Upstream blits unmanaged structs into a pooled array; the port encodes values with BatchValue (fields in declaration order, little-endian), the encoding of the batch transport, so that no unsafe is needed.

Implementations

impl RenderDataWriter

pub fn new() -> Self

pub fn length(&self) -> usize

The number of bytes written.

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

The bytes written.

pub fn reserve(&mut self, count: usize) -> &mut [u8]

Appends count bytes for the caller to fill.

pub fn rewind(&mut self, length: usize)

Drops everything written after length bytes.

pub fn write<T: BatchValue>(&mut self, value: T)

Appends a value.

pub fn write_opcode(&mut self, opcode: RenderDataOpcode)

Appends an opcode.

pub fn write_payload<T: IRenderDataPayload>(&mut self, payload: T)

Appends the opcode of a payload, then the payload.

pub fn dispose(&mut self)

Releases the buffer.

impl Debug for RenderDataWriter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for RenderDataWriter

fn default() -> Self
