Struct GlBufferHandle 

pub struct GlBufferHandle { /* private fields */ }

GL buffer object (GLuint) + binding metadata.

Implementations

impl GlBufferHandle

pub unsafe fn try_from_raw( name: u32, target: GlBufferTarget, size: u64, context: *mut c_void, share_group: Option<u64>, keep_alive: Option<KeepAlive>, ) -> Result<Self, InvalidHandleError>

Wrap a GL buffer-object name plus its binding metadata. Borrowing: the handle is stored non-owningly, this type has no Drop, and every obligation below extends to each Clone.

Safety

• name must be a buffer-object name live in context’s share group, and target its actual binding target.
• size must not exceed the buffer’s real store size in bytes — consumers read and write [0, size) through it. Zero is rejected as InvalidHandleError::ZeroSize and name == 0 as InvalidHandleError::NullHandle; neither is a caller obligation.
• The context == null meaning, the share_group obligation, the thread-affinity assertion and the lifetime rule (no retain, no Drop, no glDeleteBuffers while any Clone is reachable) are exactly those of GlTextureHandle::try_from_raw.
