update(_:)

Provides partial read-write CPU access to the transform data.

Declaration

final func update<R, E>(_ body: @_lifetime(0: copy 0) (inout MutableSpan<float4x4>) throws(E) -> R) throws(E) -> R where E : Error, R : ~Copyable

Parameters

  • body:

    A closure that receives a MutableSpan<float4x4> over the current transform data. The span is valid only for the duration of the closure.

Discussion

Use update when you want to modify a subset of transforms without fully replacing the buffer contents.
