Enum ScalarKind 

pub enum ScalarKind {
    Bool,
    Int,
    Str,
}

The leaf kinds. Deliberately the three the ABI already carries plus nothing: a float would need a parse/format round-trip that survives every locale and every plugin language’s formatter, and no option in the workspace wants one. Adding it later is additive; guessing now is not.

Variants

Bool

true / false; matched by ConfigValue::Bool.

Int

A signed 64-bit integer; matched by ConfigValue::Int.

Str

A UTF-8 string; matched by ConfigValue::Str.

Implementations

impl ScalarKind

pub fn label(self) -> &'static str

The word a mismatch message uses. Matches OptionType::type_label’s vocabulary for the three primitives, so the two surfaces do not disagree about what an integer is called.
