Struct ModuleInterner 

struct ModuleInterner {
    allocations: BTreeMap<(usize, usize), (Arc<str>, ModuleId)>,
    values: HashMap<Arc<str>, ModuleId>,
}

Intern module values once per source allocation, retaining witnesses until drop.

Fields

allocations: BTreeMap<(usize, usize), (Arc<str>, ModuleId)>

The retained Arc prevents a remembered address from being reused.

values: HashMap<Arc<str>, ModuleId>

Standard value equality handles equal allocations and hash collisions exactly.

Implementations

impl ModuleInterner

fn intern<E>( &mut self, module: Arc<str>, admit: impl FnOnce(u64) -> Result<(), E>, ) -> Result<ModuleId, E>

Admit metadata before insertion; hot allocations never hash module bytes again.

Trait Implementations

impl Default for ModuleInterner

fn default() -> ModuleInterner

Returns the “default value” for a type.
