Enum OutputFormat 

pub enum OutputFormat {
    Toon,
    Json,
    Mckp,
}

Output format for transformations.

Variants

Toon

TOON format – token-optimized custom format. Wins on cl100k_base tokenizers but loses ~26% on o200k_base (the modern Anthropic / OpenAI family). Kept as a baseline; not the recommended default. See Paper 2 §Savings Accounting.

Json

JSON pretty-printed – for programmatic processing.

Mckp

MCKP v2 – format-adaptive encoder dispatched by structural shape. Routes object-wrapping-array shapes through the union-of-keys table renderer (deep_mckp_with_inner_table) and falls back to compact JSON when no shape applies. Tokenizer-agnostic — see Paper 2 §Encoder Bug Postmortem and §Savings Accounting.

Trait Implementations

impl Clone for OutputFormat

fn clone(&self) -> OutputFormat

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OutputFormat

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

Formats the value using the given formatter.

impl PartialEq for OutputFormat

fn eq(&self, other: &OutputFormat) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
