pub enum Index<'a> {
    Num(u32Span),
    Id(Id<'a>),
}
Expand description

A reference to another item in a wasm module.

This type is used for items referring to other items (such as call $foo referencing function $foo). References can be either an index (u32) or an Id in the textual format.

The emission phase of a module will ensure that Index::Id is never used and switch them all to Index::Num.

Variants

Num(u32Span)

A numerical index that this references. The index space this is referencing is implicit based on where this Index is stored.

Id(Id<'a>)

A human-readable identifier this references. Like Num, the namespace this references is based on where this is stored.

Implementations

Returns the source location where this Index was defined.
