Variants

Block(AstBlock<'db>)

{ ... }

Literal(Literal<'db>)

22

Id(SpannedIdentifier<'db>)

x

DotId(AstExpr<'db>, SpannedIdentifier<'db>)

E.f

Note that this is not necessarily a field. Interpretation is needed.

SquareBracketOp(AstExpr<'db>, SquareBracketArgs<'db>)

E[..]

Note that we cannot parse the contents of the [..] until we have resolved the expression E.

ParenthesisOp(AstExpr<'db>, SpanVec<'db, AstExpr<'db>>)

E(expr0, expr1, ..., exprN)

Note that the callee expression could also be a DotId in which case this is a method call as well as a SquareBracketsOp.

Tuple(SpanVec<'db, AstExpr<'db>>)

(a, b, c)

Could also be (a).

Constructor(AstPath<'db>, SpanVec<'db, AstConstructorField<'db>>)

a { field: value }

Return(Option<AstExpr<'db>>)

return x

Await

x.await

Fields

future: AstExpr<'db>

await_keyword: Span<'db>

PermissionOp

x.lease, x.ref, or x.give

Fields

value: AstExpr<'db>

BinaryOp(SpannedBinaryOp<'db>, AstExpr<'db>, AstExpr<'db>)

a + b etc

UnaryOp(SpannedUnaryOp<'db>, AstExpr<'db>)

!foo etc

If(Vec<IfArm<'db>>)

Trait Implementations

impl<'db> Clone for AstExprKind<'db>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for AstExprKind<'db>

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

Formats the value using the given formatter.

impl<'db> Hash for AstExprKind<'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> Ord for AstExprKind<'db>

fn cmp(&self, other: &AstExprKind<'db>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'db> PartialEq for AstExprKind<'db>

fn eq(&self, other: &AstExprKind<'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.

impl<'db> PartialOrd for AstExprKind<'db>

fn partial_cmp(&self, other: &AstExprKind<'db>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'db> Serialize for AstExprKind<'db>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'db> Update for AstExprKind<'db>

unsafe fn maybe_update(old_pointer_: *mut Self, new_value_: Self) -> bool

Returns

impl<'db> Eq for AstExprKind<'db>

impl<'db> StructuralPartialEq for AstExprKind<'db>
