pub struct AllocationParams(/* private fields */);
Expand description

Parameters to control the allocation of memory

Implementations§

source§

impl AllocationParams

source

pub fn flags(&self) -> MemoryFlags

source

pub fn align(&self) -> usize

source

pub fn prefix(&self) -> usize

source

pub fn padding(&self) -> usize

source

pub fn new( flags: MemoryFlags, align: usize, prefix: usize, padding: usize, ) -> Self

Create a new AllocationParams on the heap. This function is for use in GStreamer language bindings. In your own code, you can just declare a AllocationParams on the stack or in a struct, and call [init()][Self::init()] to initialize it.

You do not need to call [init()][Self::init()] on the instance returned by this function.

§Returns

a new AllocationParams

source

pub fn as_ptr(&self) -> *const GstAllocationParams
