Struct DeviceMemoryCallbacks 

pub struct DeviceMemoryCallbacks {
    pub allocated: Option<unsafe extern "system" fn(DeviceHandle, DeviceMemory, u64, u32, *mut c_void)>,
    pub freed: Option<unsafe extern "system" fn(DeviceHandle, DeviceMemory, u64, u32, *mut c_void)>,
    pub p_user_data: *mut c_void,
}

Informative notifications for actual native memory allocation/free effects. Callbacks do not allocate Rust metadata and do not own the native memory.

Fields

allocated: Option<unsafe extern "system" fn(DeviceHandle, DeviceMemory, u64, u32, *mut c_void)>

freed: Option<unsafe extern "system" fn(DeviceHandle, DeviceMemory, u64, u32, *mut c_void)>

p_user_data: *mut c_void

Implementations

impl DeviceMemoryCallbacks

pub fn new() -> Self

pub fn set_allocated( self, value: Option<unsafe extern "system" fn(DeviceHandle, DeviceMemory, u64, u32, *mut c_void)>, ) -> Self

Set allocated and return the updated record.

pub fn set_freed( self, value: Option<unsafe extern "system" fn(DeviceHandle, DeviceMemory, u64, u32, *mut c_void)>, ) -> Self

Set freed and return the updated record.

pub fn set_p_user_data(self, value: *mut c_void) -> Self

Set p_user_data and return the updated record.
