Crate muon 

Muon — the Mu object notation.

A no_std scannerless parser that turns Muon text into a Muon tree, following docs/muon-spec.md. Nesting is driven by an explicit heap stack (see parse.rs), so depth is bounded only by memory. Leaves borrow from the input (&'a str, zero-copy); structure is allocated. Symbols are lexed by maximal munch, so the whitespace-merge rules of the spec fall out naturally (a run of symchars is one <sym>).

let seq = muon::parse("a b, c").unwrap();
assert_eq!(
    seq.to_json(),
    r#"{"seq":[{"chain":[{"sym":"a"},{"sym":"b"}]},{"chain":[{"sym":"c"}]}]}"#,
);

Structs

Chain

A chain: one or more juxtaposed items (<chain>). Never empty.

ParseError

A parse failure, with the byte offset into the input where it was detected.

Seq

A sequence: zero or more chains delimited by separators (<seq>).

Enums

ErrorKind

Item

A single visually-atomic entity in a chain (<item> in the spec).

Functions

parse

Parse a whole Muon file: a top-level <seq> up to end of input.
