Variants

Access(AccessExpression)

A struct access expression, e.g. Foo.bar.

Array(ArrayExpression)

An array expression, e.g., [true, false, true, false].

Binary(BinaryExpression)

A binary expression, e.g., 42 + 24.

Call(CallExpression)

A call expression, e.g., my_fun(args).

Cast(CastExpression)

A cast expression, e.g., 42u32 as u8.

Err(ErrExpression)

An expression of type “error”. Will result in a compile error eventually.

Identifier(Identifier)

An identifier.

Literal(Literal)

A literal expression.

Locator(LocatorExpression)

A locator expression, e.g., hello.aleo/foo.

Struct(StructExpression)

An expression constructing a struct like Foo { bar: 42, baz }.

Ternary(TernaryExpression)

A ternary conditional expression cond ? if_expr : else_expr.

Tuple(TupleExpression)

A tuple expression e.g., (foo, 42, true).

Unary(UnaryExpression)

An unary expression.

Unit(UnitExpression)

A unit expression e.g. ()

Implementations

impl Expression

pub(crate) fn precedence(&self) -> u32

pub(crate) fn associativity(&self) -> Associativity

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl Default for Expression

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Expression

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Expression

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

Formats the value using the given formatter.

impl Node for Expression

fn span(&self) -> Span

Returns the span of the node.

fn set_span(&mut self, span: Span)

Sets the span of the node.

fn id(&self) -> NodeID

Returns the ID of the node.

fn set_id(&mut self, id: NodeID)

Sets the ID of the node.

impl PartialEq for Expression

fn eq(&self, other: &Expression) -> 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 Serialize for Expression

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Expression

impl StructuralPartialEq for Expression
