PeekRouter

Struct PeekRouter

pub struct PeekRouter<P, T, F = RejectService> { /* private fields */ }

Available on crate feature std only.

Expand description

A generic Service router driven by a fail-fast PeekVerdict predicate.

Peeking uses a grow-on-demand heap buffer and replays all read bytes. Any outcome other than PeekVerdict::Match dispatches to the fallback.

Implementations§

impl<P, T> PeekRouter<P, T>

pub fn new(predicate: P, acceptor: T) -> PeekRouter<P, T>

Create a router that rejects non-matching input by default.

pub fn with_fallback<F>(self, fallback: F) -> PeekRouter<P, T, F>

Attach a fallback Service.

impl<P, T, F> PeekRouter<P, T, F>

pub fn maybe_with_peek_timeout( self, peek_timeout: Option<Duration>, ) -> PeekRouter<P, T, F>

Set the maximum time spent peeking into the input.

pub fn maybe_set_peek_timeout( &mut self, peek_timeout: Option<Duration>, ) -> &mut PeekRouter<P, T, F>

Set the maximum time spent peeking into the input.

pub fn with_peek_timeout(self, peek_timeout: Duration) -> PeekRouter<P, T, F>

Set the maximum time spent peeking into the input.

pub fn set_peek_timeout( &mut self, peek_timeout: Duration, ) -> &mut PeekRouter<P, T, F>

Set the maximum time spent peeking into the input.

pub fn without_peek_timeout(self) -> PeekRouter<P, T, F>

Set the maximum time spent peeking into the input.

pub fn unset_peek_timeout(&mut self) -> &mut PeekRouter<P, T, F>

Set the maximum time spent peeking into the input.

pub fn with_max_peek_size( self, max_peek_size: NonZero<usize>, ) -> PeekRouter<P, T, F>

Set the byte limit for peeking; this does not impose a time limit.

pub fn set_max_peek_size( &mut self, max_peek_size: NonZero<usize>, ) -> &mut PeekRouter<P, T, F>

Set the byte limit for peeking; this does not impose a time limit.

pub fn with_peek_read_chunk_size( self, peek_read_chunk_size: NonZero<usize>, ) -> PeekRouter<P, T, F>

Set the maximum number of bytes requested per read.

pub fn set_peek_read_chunk_size( &mut self, peek_read_chunk_size: NonZero<usize>, ) -> &mut PeekRouter<P, T, F>

Set the maximum number of bytes requested per read.

impl<T> PeekRouter<(), T>

pub fn from_prefix( prefix: &'static [u8], acceptor: T, ) -> PeekRouter<impl Clone + Fn(&[u8]), T>

Create a router matching a fixed prefix.

Peeking is limited to the prefix length unless overridden.

§Panics

Panics when prefix is empty.
