Types

type NodeType

type NodeType int

NodeType identifies the type of AST node.

const (
	// Top-level
	NodeTypeError   NodeType = iota // error occurred; value is text of error
	NodeTypeFile                    // The file root node
	NodeTypeComment                 // A single or multiline comment

	NodeTypeDefinition       // A definition.
	NodeTypeCaveatDefinition // A caveat definition.

	NodeTypeCaveatParameter  // A caveat parameter.
	NodeTypeCaveatExpression // A caveat expression.

	NodeTypeRelation   // A relation
	NodeTypePermission // A permission

	NodeTypeTypeReference         // A type reference
	NodeTypeSpecificTypeReference // A reference to a specific type.
	NodeTypeCaveatReference       // A caveat reference under a type.

	NodeTypeUnionExpression
	NodeTypeIntersectExpression
	NodeTypeExclusionExpression

	NodeTypeArrowExpression // A TTU in arrow form.

	NodeTypeIdentifier    // An identifier under an expression.
	NodeTypeNilExpression // A nil keyword

	NodeTypeCaveatTypeReference // A type reference for a caveat parameter.
