Trait Pool 

pub trait Pool: Send + Sync {
    type Permit: Send;
    type BuildPermit: Send;

    // Required methods
    fn acquire_or_reserve(
        &self,
        cancellation: &Cancellation,
    ) -> impl Future<Output = Result<Acquisition<Self::Permit, Self::BuildPermit>, Error>> + Send;
    fn begin_close(&self);
    fn stats(&self) -> Stats;
}

Shared vocabulary with distinct associated acquisition types. Resource-specific mutation and use completion stay on the concrete types.

Required Associated Types

type Permit: Send

type BuildPermit: Send

Required Methods

fn acquire_or_reserve( &self, cancellation: &Cancellation, ) -> impl Future<Output = Result<Acquisition<Self::Permit, Self::BuildPermit>, Error>> + Send

fn begin_close(&self)

fn stats(&self) -> Stats

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
