Enum Format 

#[non_exhaustive]
pub enum Format {
    Json,
    Jsonc,
    Json5,
    Yaml,
    Toml,
    Zon,
    Fig,
}

A config format. Every variant parses, edits, and serializes.

Every variant is always present in the enum, but each format is gated by a crate feature of the same name (json, yaml, toml, zon, fig). json, yaml, toml, and fig are on by default; zon is opt-in. Disabling a feature compiles that format out of the bundled native library, so selecting it then fails with Error::UnsupportedFormat at runtime. Json/Jsonc/Json5 share one core behind the json feature. (The core also has a reader-only XML format, but it has no writable Format variant and so is not exposed here.)

#[non_exhaustive]: the core gains formats over time, so a match needs a _ arm. Constructing a variant is unaffected.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Json

Jsonc

Json5

Yaml

Toml

Zon

Fig

The native fig authoring dialect (see src/languages/fig/DESIGN.md in the core repo) — a memorable, typeable surface over the same AST.
