Struct cpal::Host

pub struct Host(_);

The platform's dynamically dispatched Host type.

An instance of this Host type may represent one of any of the Hosts available on the platform.

Use this type if you require switching between available hosts at runtime.

This type may be constructed via the host_from_id function. HostIds may be acquired via the ALL_HOSTS const and the available_hosts function.
