Module query 

Central command registry with lookup and search operations.

Registry is the primary store for the command tree in an argot application. It owns a Vec<Command> and exposes several query methods:

• Registry::get_command — exact lookup by canonical name.
• Registry::get_subcommand — walk a path of canonical names into the nested subcommand tree.
• Registry::list_commands — iterate all top-level commands.
• Registry::search — case-insensitive substring search across canonical name, summary, and description.
• Registry::fuzzy_search — fuzzy (skim) search returning results sorted by score (best match first). Requires the fuzzy feature.
• Registry::to_json — serialize the command tree to pretty-printed JSON (handler closures are excluded).

Pass registry.commands() to crate::Parser::new to wire the registry into the parsing pipeline.

Example

let registry = Registry::new(vec![
    Command::builder("list").summary("List all items").build().unwrap(),
    Command::builder("get").summary("Get a single item").build().unwrap(),
]);

assert!(registry.get_command("list").is_some());
assert_eq!(registry.search("item").len(), 2);

Structs

CommandEntry

A command paired with its canonical path from the registry root.

Registry

Owns the registered command tree and provides query/search operations.

Enums

QueryError

Errors produced by Registry methods.

Functions

command_to_json_with_fields

Serialize a single Command to a pretty-printed JSON string, filtering the output to only include the requested top-level fields.

command_to_ndjson

Serialize a single Command to a compact (single-line) JSON string.
