Variants

UseStatement(UseStatement)

Tuple Fields

0: UseStatement

A statement of the form use foo::bar; or use ::foo::bar;

ReturnStatement(ReturnStatement)

Tuple Fields

0: ReturnStatement

A statement of the form return foo;

Declaration(Declaration)

Tuple Fields

0: Declaration

Any type of declaration, of which there are quite a few. See Declaration for more details on the possible variants.

Expression(Expression)

Tuple Fields

0: Expression

Any type of expression, of which there are quite a few. See Expression for more details.

ImplicitReturnExpression(Expression)

Tuple Fields

0: Expression

An implicit return expression is different from a AstNodeContent::ReturnStatement because it is not a control flow item. Therefore it is a different variant.

An implicit return expression is an Expression at the end of a code block which has no semicolon, denoting that it is the Expression to be returned from that block.

WhileLoop(WhileLoop)

Tuple Fields

0: WhileLoop

A control flow element which loops continually until some boolean expression evaluates as false.

IncludeStatement(IncludeStatement)

Tuple Fields

0: IncludeStatement

A statement of the form dep foo::bar; which imports/includes another source file.
