Implementations

impl<'db> Expr<'db>

pub fn ty(&self) -> TypeId<'db>

pub fn stable_ptr(&self) -> ExprPtr<'db>

pub fn as_member_path(&self) -> Option<ExprVarMemberPath<'db>>

Returns the member path of the expression, if it is a variable or a member access.

pub fn is_mutable_var( &self, semantic_defs: &UnorderedHashMap<VarId<'db>, Binding<'db>>, ) -> bool

Returns true if the expression is a variable or a member access of a mutable variable.

Trait Implementations

impl<'db> Clone for Expr<'db>

fn clone(&self) -> Expr<'db>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for Expr<'db>

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

Formats the value using the given formatter.

impl<'db> DebugWithDb<'db> for Expr<'db>

type Db = ExprFormatter<'db>

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

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

where Self: Sized + 'me,

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

where Self: Sized + 'me,

impl<'db> From<&Expr<'db>> for SyntaxStablePtrId<'db>

fn from(expr: &Expr<'db>) -> Self

Converts to this type from the input type.

impl<'db> Hash for Expr<'db>

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<'db> PartialEq for Expr<'db>

fn eq(&self, other: &Expr<'db>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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