Enum ExprForm 

pub enum ExprForm {
    Identifier(Identifier),
    GetAttribute(Box<ExprGetAttribute>),
    GetSubscript(Box<ExprGetSubscript>),
    Call(Box<ExprCall>),
    LiteralValue(ExprLiteral),
    TypedIdentifier(TypedIdentifier),
}

Each expression has a form, which is one of the following.

These forms are deliberately purely syntactic - additional semantic information, like types, are dependent on the feature graph, which may therefore be out-of-date when decoding an expression message.

Consumers must always perform additional parsing and validation, so semantic information should not be stored in the proto message itself.

Variants

Identifier(Identifier)

GetAttribute(Box<ExprGetAttribute>)

GetSubscript(Box<ExprGetSubscript>)

Call(Box<ExprCall>)

LiteralValue(ExprLiteral)

TypedIdentifier(TypedIdentifier)

Implementations

impl ExprForm

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

Encodes the message to a buffer.

pub fn merge( field: &mut Option<ExprForm>, 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 ExprForm

fn clone(&self) -> ExprForm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExprForm

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

Formats the value using the given formatter.

impl PartialEq for ExprForm

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