Struct WGSLFunction 

pub struct WGSLFunction {
    pub name: String,
    pub entry_point: WGSLEntryPoint,
    pub params: Vec<WGSLParam>,
    pub return_type: Option<WGSLType>,
    pub return_attrib: WGSLReturnAttrib,
    pub body: Vec<String>,
}

A WGSL function (helper or entry point).

Fields

name: String

Function name.

entry_point: WGSLEntryPoint

Entry-point kind (or None for helpers).

params: Vec<WGSLParam>

Ordered parameters.

return_type: Option<WGSLType>

Return type (None means no return value / void).

return_attrib: WGSLReturnAttrib

Optional attribute on the return type.

body: Vec<String>

Body statements.

Implementations

impl WGSLFunction

pub fn helper(name: impl Into<String>) -> Self

Create a helper function with no entry-point annotation.

pub fn vertex(name: impl Into<String>) -> Self

Create a @vertex entry-point function.

pub fn fragment(name: impl Into<String>) -> Self

Create a @fragment entry-point function.

pub fn compute(name: impl Into<String>, x: u32, y: u32, z: u32) -> Self

Create a @compute @workgroup_size(x, y, z) entry-point function.

pub fn add_param(&mut self, param: WGSLParam)

Add a parameter.

pub fn set_return_type(&mut self, ty: WGSLType)

Set the return type.

pub fn set_return_type_with_attrib( &mut self, ty: WGSLType, attrib: WGSLReturnAttrib, )

Set the return type with an attribute.

pub fn add_statement(&mut self, stmt: impl Into<String>)

Append a body statement (without trailing semicolon — the emitter adds it).

pub fn emit(&self) -> String

Emit the complete function definition.
