pub fn parse_type_ref(s: &str) -> Result<TypeRef, String>Expand description
Parse the IDL’s compact type syntax into a TypeRef.
Handles primitive names (i32, string, bytes, and so on), iterators
(iter<T>), lists ([T]), maps ({K:V}), and the optional suffix (T?).
Any other bare identifier is taken to be a user-defined record, enum,
interface, or callback interface name and returned as TypeRef::Named.
§Errors
Returns an error message when s is empty or only whitespace, when a map
type ({K:V}) is missing its : separator. The same errors propagate up
from a malformed inner type of a list, map, optional, or iterator.
