Struct pomelo_hir::FileAstIdx

pub struct FileAstIdx<N> {
    pub(crate) index: Idx<SyntaxNodePtr>,
    pub(crate) _ph: PhantomData<fn() -> N>,
}

A pointer to an AST node.

Currently, this is needed because we only hold references to SyntaxNodePtrs, which know nothing about the type of the pointed-to AST node. This nice thing is that this allows us to allocate all of the SyntaxNodePtrs in the same arena (unlike if we used the typed AstPtrs).

Fields

index: Idx<SyntaxNodePtr>

_ph: PhantomData<fn() -> N>

Trait Implementations

impl<N> Clone for FileAstIdx<N>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Debug> Debug for FileAstIdx<N>

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

Formats the value using the given formatter.

impl<N: PartialEq> PartialEq<FileAstIdx<N>> for FileAstIdx<N>

fn eq(&self, other: &FileAstIdx<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.
