Crate wordnet_db 

Load WordNet dictionaries with full fidelity and zero-copy text.

This crate ingests the canonical data.*/index.* files, preserves every field (lex_id, ss_type, pointer source/target indices, verb frames), and exposes borrowed &str slices for all text. Callers choose between memory-mapped files or owned buffers at runtime via LoadMode.

Public access is intentionally read-only (no pub fields), leaving room to evolve internal storage while keeping a stable API surface.

Features

• Zero-copy text: lemmas, pointer symbols, glosses, and indices borrow from the original bytes.
• Full-fidelity parsing: retains raw offsets, satellite adjectives, frames, and pointer source/target indices.
• Runtime backing choice: switch between mmap and owned buffers with LoadMode::Mmap / LoadMode::Owned.
• Convenience lookups: lemma existence, index entries, synset fetching, and a streaming iterator over all synsets.

Example

use wordnet_db::{LoadMode, WordNet};
use wordnet_types::Pos;

let wn = WordNet::load_with_mode("/path/to/wordnet", LoadMode::Mmap)?;
let dog_index = wn.index_entry(Pos::Noun, "dog").expect("dog in index");
println!("dog synsets: {:?}", dog_index.synset_offsets);

for sid in wn.synsets_for_lemma(Pos::Noun, "dog") {
    let syn = wn.get_synset(*sid).unwrap();
    println!("{}: {}", syn.id.offset, syn.gloss.definition);
}

For a runnable demo, see cargo run -p wordnet-db --example stats -- <dict>.
