Struct screen_13::pool::alias::AliasPool

pub struct AliasPool<T> { /* private fields */ }

A memory-efficient resource wrapper for any Pool type.

The information for each alias request is compared against the actively aliased resources for compatibility. If no acceptable resources are aliased for the information provided a new resource is leased and returned.

All regular leasing and other functionality of the wrapped pool is available through Deref and DerefMut.

NOTE: You must call alias(..) to use resource aliasing as regular lease(..) calls will not inspect or return aliased resources.

Details

• Acceleration structures may be larger than requested
• Buffers may be larger than requested or have additional usage flags
• Images may have additional usage flags

Examples

See aliasing.rs
