Enum sway_core::language::parsed::AstNodeContent

pub enum AstNodeContent {
    UseStatement(UseStatement),

    Error(Box<[Span]>, ErrorEmitted),
}

Represents the various structures that constitute a Sway program.

Variants

UseStatement(UseStatement)

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

Declaration(Declaration)

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

Expression(Expression)

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

ImplicitReturnExpression(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.

IncludeStatement(IncludeStatement)

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

Error(Box<[Span]>, ErrorEmitted)

A malformed statement.

Used for parser recovery when we cannot form a more specific node. The list of Spans are for consumption by the LSP and are, when joined, the same as that stored in statement.span.
