Enum FieldType 

#[non_exhaustive]
pub enum FieldType {
    Null,
    Bool,
    Int,
    Float,
    Str,
    Ref,
    Extended(ExtKind),
    Map,
    Seq,
}

The field-type vocabulary a fields.<name>.type declaration is spelled in, re-exported so a consumer can name types without depending on fig-schema (or, for ExtKind, on fig) directly — and so neither can drift to a different version than the one prov resolves against. The type a field expects. Drives type-directed parsing and widget choice.

#[non_exhaustive]: fig gains ExtKinds and a schema gains field shapes in ordinary releases, 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.

Null

Bool

Int

Float

Str

Ref

A link into the workspace (stored textually, like Str, but a reference).

Extended(ExtKind)

A format-specific scalar carried verbatim — a TOML datetime, a ZON enum or char literal. Coercing to one keeps the value’s native type instead of quoting it into a string, so a TOML date = 1979-05-27 survives an edit as a date rather than becoming date = "1979-05-27".

Map

Seq

Implementations

impl FieldType

pub fn coerce(self, s: &str) -> Value

Coerce an edit-buffer string to this type — the schema-directed counterpart of shape-guessing. A value that doesn’t fit the type falls back to a string (the caller’s own reparse is the final backstop); container types are not scalar-edited, so they also pass through as text.

The numeric types go through Value::parse_number, so the text fig itself writes reads back unchanged — including the .inf/.nan spellings str::parse::<f64> rejects. Those still have no representation in JSON or TOML, so an embedder targeting those formats should reject them before they reach here.
