Trait ratelimit_meter::Decider

source · 
pub trait Decider: Sized + DeciderImpl {
    fn check(&mut self) -> Result<(), NonConformance> { ... }
    fn check_at(&mut self, at: Instant) -> Result<(), NonConformance> { ... }
}
Expand description

The main decision trait. It allows checking a single cell against the rate-limiter, either at the current time instant, or at a given instant in time, updating the Decider’s internal state if the cell is conforming.

Provided Methods

Tests if a single cell can be accommodated at Instant::now(). If it can be, check updates the Decider to account for the conforming cell and returns Ok(()).

If the cell is non-conforming (i.e., it can’t be accomodated at this time stamp), check_at returns Err with information about the earliest time at which a cell could be considered conforming (see NonConformance).

Tests whether a single cell can be accommodated at the given time stamp. See check.
