Struct sway_ir::irtype::Aggregate

pub struct Aggregate(pub Index);

A collection of Types.

XXX I’ve added Array as using Aggregate in the hope ExtractValue could be used just like with struct aggregates, but it turns out we need ExtractElement (which takes an index Value). So Aggregate can be a ‘struct’ or ‘array’ but you only ever use them with Struct and Array types and with ExtractValue and ExtractElement… so they’re orthogonal and we can simplify aggregate again to be only for structs.

But also to keep Type as Copy we need to put the Array meta into another copy type (rather than recursing with Box, effectively a different Aggregate. This could be OK though, still simpler that what we have here.

Implementations

impl Aggregate

pub fn new_struct(context: &mut Context, field_types: Vec<Type>) -> Self

Return a new struct specific aggregate.

pub fn new_array(context: &mut Context, element_type: Type, count: u64) -> Self

Returna new array specific aggregate.

pub fn get_field_type(&self, context: &Context, indices: &[u64]) -> Option<Type>

Get the type of (nested) aggregate fields, if found.

pub fn get_elem_type(&self, context: &Context) -> Option<Type>

Get the type of the array element, if applicable.
