[−][src]Trait rnix::types::TypedNode

pub trait TypedNode: Clone {
    fn cast(from: SyntaxNode) -> Option<Self>;
    fn node(&self) -> &SyntaxNode;

A TypedNode is simply a wrapper around an untyped node to provide a type system in some sense.

Required methods

`fn cast(from: SyntaxNode) -> Option<Self>`

Cast an untyped node into this strongly-typed node. This will return None if the type was not correct.

`fn node(&self) -> &SyntaxNode`

Return a reference to the inner untyped node

Provided methods

`fn errors(&self) -> Vec<SyntaxElement>`

Return all errors of all children, recursively

`fn first_token(&self) -> Option<SyntaxToken>`

Return the first non-trivia token

`fn dump(&self) -> TextDump`

Return a dump of the AST. One of the goals is to be a stable format that can be used in tests.
