Lease

This crate provides a Pool struct that allows taking Leasees and using them. When a Lease is dropped it is automatically returned to the pool.

One nice thing about this api is that the lifetime of a Lease is not connected to the lifetime of a Pool so they can be sent across threads.

There is also an InitPool that ensures that all new leases are created the same way

A LockedPool only allows calling functions that do not add or remove any Leases

Features

  • async
    • Enables the [Pool::get()] function. Async brings a little bit of overhead to getting leases so it is behind a feature.
    • Enables the [Pool::stream()] function that allows getting a stream of leases as they become available
