[]Struct gstreamer::Allocator

pub struct Allocator(_, _);

Memory is usually created by allocators with a AllocatorExt::alloc method call. When None is used as the allocator, the default allocator will be used.

New allocators can be registered with Allocator::register. Allocators are identified by name and can be retrieved with Allocator::find. AllocatorExt::set_default can be used to change the default allocator.

New memory can be created with Memory::new_wrapped that wraps the memory allocated elsewhere.

Methods

impl Allocator[src]

pub fn find(name: Option<&str>) -> Option<Allocator>[src]

Find a previously registered allocator with name. When name is None, the default allocator will be returned.

name

the name of the allocator

Returns

a Allocator or None when the allocator with name was not registered. Use GstObjectExt::unref to release the allocator after usage.

pub fn register<P: IsA<Allocator>>(name: &str, allocator: &P)[src]

Registers the memory allocator with name. This function takes ownership of allocator.

name

the name of the allocator
