IdentExpr(Ident)

An identifier expression.

SelectExpr(Box<Select>)

A field selection expression, e.g. request.auth.

CallExpr(Box<Call>)

A call expression, including calls to predefined functions and operators.

ListExpr(CreateList)

StructExpr(CreateStruct)

A map or message creation expression.

ComprehensionExpr(Box<Comprehension>)

Implementations

impl ExprKind

pub fn encode(&self, buf: &mut impl BufMut)

Encodes the message to a buffer.

pub fn merge( field: &mut Option<ExprKind>, tag: u32, wire_type: WireType, buf: &mut impl Buf, ctx: DecodeContext, ) -> Result<(), DecodeError>

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for ExprKind

fn clone(&self) -> ExprKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExprKind

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

Formats the value using the given formatter.

impl PartialEq for ExprKind

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