Module spirv_std::arch

SPIR-V Instrinics

This module is intended as a low level abstraction over SPIR-V instructions. These functions will typically map to a single instruction, and will perform no additional safety checks beyond type-checking.

Functions

all	Result is true if all components of vector is true, otherwise result is false.
any	Result is true if any component of vector is true, otherwise result is false.
ddx	Returns the partial derivative of Self with respect to the window’s X coordinate. Returns the same result as either [Self::ddx_fine] or [Self::ddx_coarse], selection of which one is dependent on external factors.
ddx_coarse	Returns the partial derivative of Self with respect to the window’s X coordinate. Uses local differencing based on the value of Self for the current fragment’s neighbors, and possibly, but not necessarily, includes the value of Self for the current fragment. That is, over a given area, the implementation can compute X derivatives in fewer unique locations than would be allowed by [Self::ddx_fine].
ddx_coarse_vector	Returns the partial derivative of Self with respect to the window’s X coordinate. Uses local differencing based on the value of Self for the current fragment’s neighbors, and possibly, but not necessarily, includes the value of Self for the current fragment. That is, over a given area, the implementation can compute X derivatives in fewer unique locations than would be allowed by [Self::ddx_fine].
ddx_fine	Returns the partial derivative of Self with respect to the window’s X coordinate. Uses local differencing based on the value of Self for the current fragment and its immediate neighbor(s).
