PeekPolicy

rama::io::peek

Struct PeekPolicy 

pub struct PeekPolicy { /* private fields */ }
Available on crate feature std only.
Expand description

Decides what a PeekCutoff does, given the PeekProgress of the peek.

Distinguishing idle from partial input separates two cases a single timeout cannot: a peer that never speaks first (e.g. a server-first protocol) versus a peer that started a protocol message and is slow to complete it.

Definitive verdicts (match, reject, EOF, size limits) are not affected.

Implementations§

§

impl PeekPolicy

pub const FAIL_OPEN: PeekPolicy

Timeouts invoke the fallback.

An interrupt invokes the fallback for idle input and is ignored for partial input. This is the default.

pub const FAIL_CLOSED: PeekPolicy

Timeouts fail the peek.

Interrupts behave as in Self::FAIL_OPEN.

pub const fn action( &self, cutoff: PeekCutoff, progress: PeekProgress, ) -> PeekAction

The PeekAction for cutoff at progress.

pub const fn with_timeout_idle(self, action: PeekAction) -> PeekPolicy

Set the action for a timeout before any byte was peeked.

pub fn set_timeout_idle(&mut self, action: PeekAction) -> &mut PeekPolicy

Set the action for a timeout before any byte was peeked.

pub const fn with_timeout_partial(self, action: PeekAction) -> PeekPolicy

Set the action for a timeout after a partial peek.

pub fn set_timeout_partial(&mut self, action: PeekAction) -> &mut PeekPolicy

Set the action for a timeout after a partial peek.

pub const fn with_interrupt_idle(self, action: PeekAction) -> PeekPolicy

Set the action for an interrupt before any byte was peeked.

pub fn set_interrupt_idle(&mut self, action: PeekAction) -> &mut PeekPolicy

Set the action for an interrupt before any byte was peeked.

pub const fn with_interrupt_partial(self, action: PeekAction) -> PeekPolicy

Set the action for an interrupt after a partial peek.

pub fn set_interrupt_partial(&mut self, action: PeekAction) -> &mut PeekPolicy

Set the action for an interrupt after a partial peek.
