Admission

Struct Admission 

Source
pub struct Admission { /* private fields */ }
Expand description

What a source does with an item the runtime has not accepted yet.

A source declares its policy through the _with form of its subscription constructor and otherwise gets Admission::bounded at the default capacity. The runtime’s own sources carry the policies the runtime gives them and take no admission from the application.

use urushi_tui_app::Admission;

assert_eq!(Admission::default(), Admission::bounded(64));
assert_ne!(Admission::latest(), Admission::bounded(1));

Implementations§

Source§

impl Admission

Source

pub const fn bounded(capacity: usize) -> Self

A FIFO of at most capacity unaccepted items.

The source waits while the queue is full, which is what makes a fast source slow down rather than the runtime grow without bound. A capacity of zero would admit nothing, so it is read as one.

Source

pub const fn latest() -> Self

One unaccepted slot, which a newer item replaces.

The source never waits, and an item the runtime did not accept before the next arrived is dropped. This suits an observation whose older value carries nothing once a newer one exists.
