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 Expression
s that use its
value.
named_expressions: FastIndexMap<Handle<Expression>, String>
Map of expressions that have associated variable names
body: Block
Block of instructions comprising the body of the function.
Implementations§
source§impl Function
impl Function
sourcepub fn originating_global(
&self,
pointer: Handle<Expression>
) -> Option<Handle<GlobalVariable>>
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
.
