Struct iota_metrics::monitored_mpsc::Permit

source · 
pub struct Permit<'a, T> { /* private fields */ }
Expand description

A newtype for an mpsc::Permit which allows us to inject gauge accounting in the case the permit is dropped w/o sending

Implementations§

source§

impl<'a, T> Permit<'a, T>

source

pub fn new( permit: Permit<'a, T>, inflight_ref: &'a Option<IntGauge>, sent_ref: &'a Option<IntGauge>, ) -> Permit<'a, T>

Creates a new Permit instance using the provided mpsc::Permit, as well as optional references to IntGauge values for tracking inflight and sent items. The Permit allows sending a message into a channel, while the optional gauges can be used to track resource utilization and activity.

source

pub fn send(self, value: T)

Sends a value into the channel using the held Permit. After successfully sending the value, it increments the sent gauge (if available) to reflect that an item has been sent. Uses std::mem::forget(self) to skip the drop logic of the permit, ensuring that unnecessary decrement operations are avoided, and thus maintaining proper resource tracking.
