NodeSchema

Defined in: src/schema/index.ts:496

A node definition schema.

Generic parameters capture the literal types needed for compile-time grammar computation:

• TName: The unique node name (e.g., “add”, “ternary”)
• TPattern: The pattern elements as a tuple type
• TPrecedence: The precedence level (non-negative integer)
• TResultType: binding name, arktype string def, object def, or undefined (allowed only for passthrough patterns)

Type Parameters

TName

TName extends string = string

TPattern

TPattern extends readonly PatternSchema[] = readonly PatternSchema[]

TPrecedence

TPrecedence extends Precedence = Precedence

TResultType

TResultType extends ResultSpec | undefined = ResultSpec | undefined

Param

values

The named bindings as memoized thunks (evaluation is uniformly lazy — call a binding to evaluate it; untaken branches are never evaluated)
