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

Implementations

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

pointer for info
