impl Memory

source

pub fn with_size(size: usize) -> Self

source

pub fn with_size_and_params(size: usize, params: &AllocationParams) -> Self

source

pub fn into_mapped_memory_readable(self) -> Result<MappedMemory<Readable>, Self>

Fill info with the pointer and sizes of the memory in self that can be accessed according to flags.

This function can return false for various reasons:

  • the memory backed by self is not accessible with the given flags.
  • the memory was already mapped with a different mapping.

info and its contents remain valid for as long as self is valid and until gst_memory_unmap() is called.

For each into_mapped_memory_readable() call, a corresponding gst_memory_unmap() call should be done.

§flags

mapping flags

§Returns

true if the map operation was successful.

§info
