示例1: scopeStructuralNewCloneExpression

// scopeStructuralNewCloneExpression scopes a structural new expression for constructing a new instance
// of a structural type by cloning and modifying an existing one.
func (sb *scopeBuilder) scopeStructuralNewCloneExpression(node compilergraph.GraphNode, childScope *proto.ScopeInfo, context scopeContext) proto.ScopeInfo {
	resolvedTypeRef := childScope.ResolvedTypeRef(sb.sg.tdg)
	if !resolvedTypeRef.IsRefToStruct() {
		sb.decorateWithError(node, "Cannot clone and modify non-structural type %s", resolvedTypeRef)
		return newScope().Invalid().GetScope()
	}

	_, isValid := sb.scopeStructuralNewEntries(node, context)
	return newScope().
		IsValid(isValid).
		Resolving(resolvedTypeRef).
		WithLabel(proto.ScopeLabel_STRUCTURAL_UPDATE_EXPR).
		GetScope()
}

示例2: scopeDeclaredValue

// scopeDeclaredValue scopes a declared value (variable statement, variable member, type field).
func (sb *scopeBuilder) scopeDeclaredValue(node compilergraph.GraphNode, title string, option requiresInitializerOption, exprPredicate compilergraph.Predicate, context scopeContext) proto.ScopeInfo {
	var exprScope *proto.ScopeInfo = nil

	exprNode, hasExpression := node.TryGetNode(exprPredicate)
	if hasExpression {
		// Scope the expression.
		exprScope = sb.getScope(exprNode, context)
		if !exprScope.GetIsValid() {
			return newScope().Invalid().GetScope()
		}
	}

	// Load the declared type, if any.
	declaredType, hasDeclaredType := sb.getDeclaredVariableType(node)
	if !hasDeclaredType {
		if exprScope == nil {
			panic("Somehow ended up with no declared type and no expr scope")
		}

		return newScope().Valid().AssignableResolvedTypeOf(exprScope).GetScope()
	}

	// Compare against the type of the expression.
	if hasExpression {
		exprType := exprScope.ResolvedTypeRef(sb.sg.tdg)
		if serr := exprType.CheckSubTypeOf(declaredType); serr != nil {
			sb.decorateWithError(node, "%s '%s' has declared type '%v': %v", title, node.Get(parser.NodeVariableStatementName), declaredType, serr)
			return newScope().Invalid().GetScope()
		}
	} else if option == requiresInitializer {
		// Make sure if the type is non-nullable that there is an expression.
		if !declaredType.IsNullable() {
			sb.decorateWithError(node, "%s '%s' must have explicit initializer as its type '%v' is non-nullable", title, node.Get(parser.NodeVariableStatementName), declaredType)
			return newScope().Invalid().Assignable(declaredType).GetScope()
		}
	}

	return newScope().Valid().Assignable(declaredType).GetScope()
}
