Struct walrus::IdsToIndices

pub struct IdsToIndices { /* private fields */ }

Maps our high-level identifiers to the raw indices they end up emitted at.

As we lower to raw wasm structures, we cement various constructs’ locations in their respective index spaces. For example, a type with some id A ends up being the i^th type emitted in the raw wasm type section. When a function references that type, it needs to reference it by its i index since the identifier A doesn’t exist at the raw wasm level.
