Struct QNameTable 

pub struct QNameTable { /* private fields */ }

Chained hash table that deduplicates QNameAtom values.

Index 0 is always EMPTY_QNAME and is never placed into any bucket. The internal hash used for bucket placement hashes the four identity fields (local_name, namespace_uri, prefix, local_name_hash) so that atoms differing only in prefix land in different buckets when possible, avoiding long chains.

Implementations

impl QNameTable

pub fn new() -> Self

Creates a new table with EMPTY_QNAME at index 0.

pub fn atomize(&mut self, qname: QNameAtom) -> u32

Inserts qname into the table if not already present, returning its index.

Deduplication compares the four identity fields (including prefix, but excluding qualified_name_idx).

pub fn get(&self, idx: u32) -> QNameAtom

Returns the QNameAtom at the given index.

Panics

Panics if idx is out of range.

Trait Implementations

impl Default for QNameTable

fn default() -> Self

Returns the “default value” for a type.
