Available on crate features MTLResourceViewPool and MTLTextureViewPool only.

A pool of lightweight texture views.

Use texture view pools to create lightweight texture view objects of MTLTexture and MTLBuffer instances.

Provided Methods

unsafe fn setTextureView_atIndex( &self, texture: &ProtocolObject<dyn MTLTexture>, index: NSUInteger, ) -> MTLResourceID

where Self: Sized + Message,

Available on crate features MTLAllocation and MTLResource and MTLTexture and MTLTypes only.

Copies a default texture view to a slot in this texture view pool at an index provided.

• Parameters:
• texture: An MTLTexture instance for which to copy its texture view.
• index: An index of a slot in this texture pool into which this method copies the texture view.
• Returns: The MTLResourceID of a newly created texture view in this pool.

Safety

• texture may need to be synchronized.
• texture may be unretained, you must ensure it is kept alive while in use.
• index might not be bounds-checked.

unsafe fn setTextureView_descriptor_atIndex( &self, texture: &ProtocolObject<dyn MTLTexture>, descriptor: &MTLTextureViewDescriptor, index: NSUInteger, ) -> MTLResourceID

where Self: Sized + Message,

Available on crate features MTLAllocation and MTLResource and MTLTexture and MTLTypes only.

Creates a new lightweight texture view.

This method creates a lightweight texture view over a texture according to a descriptor you provide. It then associates the texture view with a slot in this texture view pool at the index you specify.

• Parameters:
• texture: An MTLTexture instance for which to create a new lightweight texture view.
• descriptor: A descriptor specifying properties of the texture view to create.
• index: An index of a slot in the texture pool into which this method writes the new texture view.
• Returns: The MTLResourceID of a newly created texture view in this pool.

Safety

• texture may need to be synchronized.
• texture may be unretained, you must ensure it is kept alive while in use.
• index might not be bounds-checked.

unsafe fn setTextureViewFromBuffer_descriptor_offset_bytesPerRow_atIndex( &self, buffer: &ProtocolObject<dyn MTLBuffer>, descriptor: &MTLTextureDescriptor, offset: NSUInteger, bytes_per_row: NSUInteger, index: NSUInteger, ) -> MTLResourceID

where Self: Sized + Message,

Available on crate features MTLAllocation and MTLBuffer and MTLResource and MTLTexture and MTLTypes only.

Creates a new lightweight texture view of a buffer.

This method creates a lightweight texture view over a buffer, according to a descriptor you provide. It then associates the texture view with a slot in this texture view pool at the index you specify.

• Parameters:
• buffer: An MTLBuffer instance for which to create a new texture view.
• descriptor: A descriptor specifying properties of the texture view to create.
• offset: A byte offset, within the buffer parameter, at which the data for the texture view starts.
• bytesPerRow: The number of bytes between adjacent rows of pixels in the source buffer’s memory.
• index: An index of a slot in the table into which this method writes the new texture view.
• Returns: The MTLResourceID of a new buffer view in this pool.

Safety

• buffer may need to be synchronized.
• buffer may be unretained, you must ensure it is kept alive while in use.
• buffer contents should be of the correct type.
• offset might not be bounds-checked.
• index might not be bounds-checked.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
