Struct FrameReaderBuilder 

pub struct FrameReaderBuilder { /* private fields */ }

Builder for FrameReader.

Implementations

impl FrameReaderBuilder

pub fn buffer_capacity(self, n: usize) -> FrameReaderBuilder

ReadBuf capacity. Default: 1MB.

pub fn pre_padding(self, n: usize) -> FrameReaderBuilder

ReadBuf pre-padding. Default: 16.

pub fn post_padding(self, n: usize) -> FrameReaderBuilder

ReadBuf post-padding. Default: 4.

pub fn message_capacity(self, n: usize) -> FrameReaderBuilder

Pre-allocate message assembly buffer. Default: 4KB.

pub fn compact_at(self, fraction: f64) -> FrameReaderBuilder

Fraction of buffer capacity consumed before proactive compaction.

When the read head has advanced past this fraction of the buffer, should_compact() returns true. This spreads compaction cost across messages instead of concentrating it in a single stall when the buffer runs out of spare room.

• 1.0: never proactively compact — only when spare is empty.
• 0.5 (default): compact when half the buffer has been consumed.
• 0.0: compact on every recv after the first byte is consumed (degenerate — not useful in practice).

Lower values reduce tail latency at the cost of more frequent (but smaller) memmoves.

pub fn max_frame_size(self, n: u64) -> FrameReaderBuilder

Maximum single frame payload. Default: 16MB.

pub fn max_message_size(self, n: usize) -> FrameReaderBuilder

Maximum assembled message size. Default: 16MB.

pub fn role(self, r: Role) -> FrameReaderBuilder

Connection role. Default: Server.

pub fn build(self) -> FrameReader

Build the reader.
