Struct TcpAcceptQueueSize 

pub struct TcpAcceptQueueSize(/* private fields */);

Accept-queue depth requested for each published TCP port’s host listener.

Valid values are 1..=i32::MAX, the positive range listen(2) accepts. The host kernel clamps the request to its own ceiling – net.core.somaxconn on Linux (4096 by default), kern.ipc.somaxconn on macOS (128 by default) – so asking for more than the host allows is not an error; it simply has no further effect until that ceiling is raised.

Implementations

impl TcpAcceptQueueSize

pub const DEFAULT: Self

Size used when none is configured.

Deeper than the 128 that TcpListener::bind would inherit from mio, so the queue can absorb a burst of parallel connections – such as a reverse proxy fanning out one page load of a modern web app – while the accept loop drains it.

pub const MAX: u32

Largest accepted value; listen(2) takes a signed int.

pub const fn get(self) -> u32

Return the requested size.
