Struct DirectSource

Source

pub struct DirectSource<'a, D: 'static> { /* private fields */ }

Available on crate features runtime and component-model and component-model-async only.

Expand description

Represents a write to a stream<u8>, providing direct access to the writer’s buffer.

Implementations§

Source §

impl<D: 'static> DirectSource<'_, D>

Source

pub fn remaining(&mut self) -> &[u8] ⓘ

Provide direct access to the writer’s buffer.

Source

pub fn mark_read(&mut self, count: usize)

Mark the specified number of bytes as read from the writer’s buffer.

This will panic if the count is larger than the size of the buffer returned by Self::remaining.
