Struct IOFileHandle 

pub struct IOFileHandle(/* private fields */);

Handle to a file for IO operations.

C++ equivalent: MTL::IOFileHandle

Implementations

impl IOFileHandle

pub unsafe fn from_raw(ptr: *mut c_void) -> Option<Self>

Create from a raw pointer.

Safety

The pointer must be a valid Metal IO file handle.

pub fn as_raw(&self) -> *mut c_void

Get the raw pointer.

pub fn label(&self) -> Option<String>

Get the label.

C++ equivalent: NS::String* label() const

pub fn set_label(&self, label: &str)

Set the label.

C++ equivalent: void setLabel(const NS::String*)
