impl<T: PodRawValue> RawWrapper for PodChoiceRef<T>

type CType = spa_pod_choice

External type

fn as_raw_ptr(&self) -> *mut Self::CType

Raw ptr to the external type

fn as_raw(&self) -> &Self::CType

Wrapped external value

fn from_raw(raw: Self::CType) -> Self

Creates wrapper from the external value, can be use when external type has no raw pointers.

unsafe fn mut_from_raw_ptr<'lft>(raw: *mut Self::CType) -> &'lft mut Self

Cast external pointer to the borrowed mutable wrapper. Panic when pointer is null. Lifetime is not reliable and should be guaranteed explicitly.

unsafe fn from_raw_ptr<'a>(raw: *const Self::CType) -> &'a Self

Cast external pointer to the borrowed wrapper. Panic when pointer is null. Lifetime is not reliable and should be guaranteed explicitly.

fn as_ptr(&self) -> *mut Self

Raw mutable pointer to Self
