Struct pipewire_wrapper::spa::buffers::meta::MetaRef

#[repr(transparent)]
pub struct MetaRef { /* private fields */ }

A metadata element.

This structure is available on the buffer structure and contains the type of the metadata and a pointer/size to the actual metadata itself.

Implementations

impl MetaRef

pub fn type_(&self) -> MetaType

pub fn set_type(&mut self, type_: MetaType)

pub fn size(&self) -> u32

pub fn set_size(&mut self, size: u32)

pub fn data(&self) -> MetaData<'_>

Trait Implementations

impl Debug for MetaRef

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<MetaRef> for spa_meta

fn from(value: MetaRef) -> Self

Converts to this type from the input type.

impl From<spa_meta> for MetaRef

fn from(value: spa_meta) -> Self

Converts to this type from the input type.

impl RawWrapper for MetaRef

type CType = spa_meta

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
