Struct MetalBufferHandle 

pub struct MetalBufferHandle { /* private fields */ }

MTLBuffer*.

Implementations

impl MetalBufferHandle

pub unsafe fn try_from_raw( buf: *mut c_void, row_pitch: u32, registry_id: Option<u64>, keep_alive: Option<KeepAlive>, ) -> Result<Self, InvalidHandleError>

Wrap a raw id<MTLBuffer>. Borrowing: the handle is stored non-owningly, this type has no Drop, and every obligation below extends to each Clone.

Safety

• buf must be a live Objective-C object conforming to MTLBuffer. Null is rejected as InvalidHandleError::NullPointer and is not a caller obligation.
• row_pitch must be the real row stride in bytes when the buffer carries image rows; consumers index rows by it, so an under-sized value reads a shifted image and an over-sized one runs off the end of [MTLBuffer length].
• Refcount, lifetime, registry_id and cross-thread obligations are exactly those of MetalTextureHandle::try_from_raw: no retain, no Drop, the producer’s strong reference must outlive every Clone.
