Functions

crate_hash

Extract the crate hash from a unique_crate_identifier (see crate_name).

crate_name

Extract the crate name from a unique_crate_identifier, which is encoded as "{crate_name}-{hash}" (the hash contains no -).

dynamic_union_variant

escape_string

free_function

free_function_export_name

mangled_symbol

Append the per-crate hash to a wasm shim symbol so that identically named exports from different crates (or different versions of one crate) cannot collide at link time. The macro emits every export shim under this mangled name; cli-support recomputes it from the hash carried in Program::unique_crate_identifier and renames the export back to its canonical name once matched.

module_mangled_symbol

mangled_symbol further qualified by the defining module, for wasm symbols of items that may share a name across modules of one crate. The macro only learns the module path from rustc, so it emits this as concat!(module_mangled_symbol(base, hash, ""), module_path!()).

module_path_hash

FNV-1a hash of a module_path!(), carried by type descriptors to identify the defining module. A const fn so the macro can fold it into a constant: the descriptor interpreter cannot read static data, so the string itself cannot be informed at runtime. The macro (through wasm_bindgen::__rt) and the CLI must both use this one function.

new_function

qualified_name

Compute a “qualified name” by prepending the namespace (joined with __) to the js_name. When there is no namespace, this returns the js_name unchanged. This is used to disambiguate internal wasm symbols when the same js_name appears in different namespaces. __ is used as the separator because double underscores are unlikely to appear in user-defined names.

struct_field_get

struct_field_set

struct_function_export_name

unwrap_function

upcast_function

Symbol name of the wasm export that upcasts a *const WasmRefCell<Child> pointer to a cloned Rc<WasmRefCell<Parent>> raw pointer. Used by the macro codegen and by cli-support’s JS emission to call each other.
