Fields

type_: u32

< memory type, one of enum spa_data_type, when allocating memory, the type contains a bitmask of allowed types. SPA_ID_INVALID is a special value for the allocator to indicate that the other side did not explicitly specify any supported data types. It should probably use a memory type that does not require special handling in addition to simple mmap/munmap.

flags: u32

< data flags

fd: i64

< optional fd for data

mapoffset: u32

< offset to map fd at

maxsize: u32

< max size of data

data: *mut c_void

< optional data pointer

chunk: *mut spa_chunk

< valid chunk of memory

Trait Implementations

impl Clone for spa_data

fn clone(&self) -> spa_data

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for spa_data

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

Formats the value using the given formatter.

impl PartialEq for spa_data

fn eq(&self, other: &spa_data) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
