Struct Gep 

pub struct Gep {
    pub base: LocalValueId,
    pub offset: usize,
}

Computes the address of a struct field: gep(base, offset) ≡ base + offset, but the result is typed PtrTo<field.type> and prints by field name instead of the raw offset.

Unlike Extract — which projects a field value out of an in-register aggregate — Gep does no memory access: it is pure pointer arithmetic. The field value is obtained by a separate load of the Gep result. The field name is recovered from the pointee of base’s StructPointer type, keyed by the byte offset.

Fields

base: LocalValueId

offset: usize

Implementations

impl Gep

pub fn field_name<'a>( &self, ctx: &'a Context<'_>, func: FunctionId, ) -> Option<&'a str>

The name of the field this Gep addresses, recovered from the nominal struct that base points at. None if base is not a typed struct pointer or the offset matches no field.

pub fn field_name_view<'ctx, 'str: 'ctx>( &self, view: impl QCodeView<'ctx, 'str>, func: FunctionId, ) -> Option<&'ctx str>
