Expand description

Helper structure that stores data needed when writing the function

Fields§

§ty: FunctionType

The current function being written

§info: &'a FunctionInfo

Analysis about the function

§expressions: &'a Arena<Expression>

The expression arena of the current function being written

§named_expressions: &'a FastIndexMap<Handle<Expression>, String>

Map of expressions that have associated variable names

Implementations§

source§

impl FunctionCtx<'_>

source

pub fn resolve_type<'a>( &'a self, handle: Handle<Expression>, types: &'a UniqueArena<Type> ) -> &'a TypeInner

Helper method that resolves a type of a given expression.

source

pub const fn name_key(&self, local: Handle<LocalVariable>) -> NameKey

Helper method that generates a NameKey for a local in the current function

source

pub const fn argument_key(&self, arg: u32) -> NameKey

Helper method that generates a NameKey for a function argument.

§Panics
  • If the function arguments are less or equal to arg
source

pub fn is_fixed_function_input( &self, expression: Handle<Expression>, module: &Module ) -> Option<BuiltIn>

Returns true if the given expression points to a fixed-function pipeline input.
