Enum ArgType 

pub enum ArgType {
    String,
    Path,
    Int,
    Duration,
    Var,
    KeyValue,
    OneOf(&'static [&'static str]),
    Rest(&'static ArgType),
}

Closed vocabulary for argument value types.

The closed enum keeps the vocabulary compiler-checked and lets docs-gen link each type cell to its reference section instead of printing bare words like duration with no explanation.

Variants

String

Path

Int

Duration

Var

KeyValue

OneOf(&'static [&'static str])

Inline alternation for one-off enums (e.g. SNAPSHOT|LOCAL). Self-describing, so it renders unlinked.

Rest(&'static ArgType)

Trailing variadic repetition (e.g. RUN’s string...).

Implementations

impl ArgType

pub fn label(&self) -> String

Table-cell label for the argument table’s Type column. Always a real crate::ast::TypeKind name — never a shape. Reference and assignment shapes ($var, KEY=value) display as the STRING values they bind or resolve to; the $/assignment requirement itself lives in the argument description and command syntax.

pub fn anchor(&self) -> Option<String>

Anchor of the type’s reference section, delegated to crate::ast::TypeKind. Only types with a TypeKind reference section link; argument shapes ($var, KEY=value) and inline alternations render unlinked.

pub fn validate_literal(&self, literal: &str) -> Result<()>

Validate a statically-known literal against this type. Templates and variables are never passed here — see check_arg.

pub fn check_arg(&self, arg: &Arg) -> Result<CheckOutcome>

Classify one positional arg for lower-time checking. Static literals validate now; templates, variables (except a $var where Var is required), and mixed fragments defer to the runtime resolvers, which see interpolated values.
