Implementations

impl SyntaxStablePtrId

pub fn lookup(&self, db: &dyn SyntaxGroup) -> SyntaxNode

Lookups a syntax node using a stable syntax pointer. Should only be called on the root from which the stable pointer was generated.

pub fn file_id(&self, db: &dyn SyntaxGroup) -> FileId

pub fn parent(&self, db: &dyn SyntaxGroup) -> SyntaxStablePtrId

Returns the stable pointer of the parent of this stable pointer.

pub fn nth_parent(&self, db: &dyn SyntaxGroup, n: usize) -> SyntaxStablePtrId

Returns the stable pointer of the nth parent of this stable pointer. n = 0: returns itself. n = 1: return the parent. n = 2: return the grand parent. And so on…

Trait Implementations

impl Clone for SyntaxStablePtrId

fn clone(&self) -> SyntaxStablePtrId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SyntaxStablePtrId

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

Formats the value using the given formatter.

impl<T: ?Sized + Upcast<dyn SyntaxGroup + 'static>> DebugWithDb<T> for SyntaxStablePtrId

fn fmt(&self, f: &mut Formatter<'_>, db: &T) -> Result

fn debug<'me, 'db>(&'me self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

fn into_debug<'me, 'db>(self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

impl Hash for SyntaxStablePtrId

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 InternKey for SyntaxStablePtrId

fn from_intern_id(salsa_id: InternId) -> Self

Create an instance of the intern-key from a u32 value.

fn as_intern_id(&self) -> InternId

Extract the u32 with which the intern-key was created.

impl PartialEq for SyntaxStablePtrId

fn eq(&self, other: &SyntaxStablePtrId) -> 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.
