Struct NameTrie 

pub struct NameTrie { /* private fields */ }

A trie over the /-separated segments of Mangle name constants.

Implementations

impl NameTrie

pub fn new() -> Self

pub fn add(&mut self, name: &str)

Inserts a name path (e.g. “/foo/bar”) into the trie.

pub fn contains(&self, name: &str) -> bool

Returns true if the exact name is in the trie.

pub fn prefix_name(&self, name: &str) -> String

Finds the longest prefix of name that exists in the trie. Returns the prefix as a name string, or /name if no prefix found.

Example: if trie contains /animal and /animal/dog, and we look up /animal/dog/poodle, returns /animal/dog.

pub fn collect(&mut self, ir: &Ir, id: InstId)

Collects all name constants from a type expression into this trie.

Special handling for fn:TaggedUnion: skips the tag field (arg 0) and tag values (odd-indexed args), only recurses into variant struct types (even-indexed args from index 2).

Trait Implementations

impl Debug for NameTrie

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NameTrie

fn default() -> NameTrie

Returns the “default value” for a type.
