Struct ra_ap_syntax::AstPtr

pub struct AstPtr<N: AstNode> { /* private fields */ }

Like SyntaxNodePtr, but remembers the type of node.

Implementations

impl<N: AstNode> AstPtr<N>

pub fn new(node: &N) -> AstPtr<N>

pub fn to_node(&self, root: &SyntaxNode) -> N

pub fn syntax_node_ptr(&self) -> SyntaxNodePtr

pub fn text_range(&self) -> TextRange

pub fn cast<U: AstNode>(self) -> Option<AstPtr<U>>

pub fn upcast<M: AstNode>(self) -> AstPtr<M>where N: Into<M>,

pub fn try_from_raw(raw: SyntaxNodePtr) -> Option<AstPtr<N>>

Like SyntaxNodePtr::cast but the trait bounds work out.

Trait Implementations

impl<N: AstNode> Clone for AstPtr<N>

fn clone(&self) -> AstPtr<N>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<N: Debug + AstNode> Debug for AstPtr<N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<N: AstNode> From<AstPtr<N>> for SyntaxNodePtr

fn from(ptr: AstPtr<N>) -> SyntaxNodePtr

Converts to this type from the input type.

impl<N: AstNode> Hash for AstPtr<N>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<N: AstNode> PartialEq<AstPtr<N>> for AstPtr<N>

fn eq(&self, other: &AstPtr<N>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
