Struct KhalBuilder 

pub struct KhalBuilder { /* private fields */ }

Configures and runs the SPIR-V and PTX shader compilation pipeline.

Used in build.rs scripts to compile a shader crate before the host crate.

Implementations

impl KhalBuilder

pub fn new( shader_crate: impl AsRef<Path>, enable_builtin_features: bool, ) -> Self

Creates a new builder for the given shader crate directory. If enable_builtin_features is true, platform-specific features are auto-detected.

pub fn rust_min_stack(self, stack: u32) -> Self

Sets the RUST_MIN_STACK environment variable for the shader compilation processes.

pub fn shader_src(self, src: impl AsRef<Path>) -> Self

Overrides the shader source directory (defaults to <shader_crate>/src).

pub fn feature(self, feature: impl ToString) -> Self

Adds a cargo feature to enable when building the shader crate.

pub fn build(self, output_dir: impl AsRef<Path>)

Compiles the shader crate and writes output files to output_dir.
