Expand description

A function defined in the module.

Fields§

§name: Option<String>

Name of the function, if any.

§arguments: Vec<FunctionArgument>

Information about function argument.

§result: Option<FunctionResult>

The result of this function, if any.

§local_variables: Arena<LocalVariable>

Local variables defined and used in the function.

§expressions: Arena<Expression>

Expressions used inside this function.

An Expression must occur before all other Expressions that use its value.

§named_expressions: IndexMap<Handle<Expression>, String, BuildHasherDefault<FxHasher>>

Map of expressions that have associated variable names

§body: Block

Block of instructions comprising the body of the function.

Implementations§

source§

impl Function

source

pub fn originating_global( &self, pointer: Handle<Expression> ) -> Option<Handle<GlobalVariable>>

Return the global variable being accessed by the expression pointer.

Assuming that pointer is a series of Access and AccessIndex expressions that ultimately access some part of a GlobalVariable, return a handle for that global.

If the expression does not ultimately access a global variable, return None.
