Struct gapi_grpc::google::api::expr::v1alpha1::Constant

pub struct Constant {
    pub constant_kind: Option<ConstantKind>,
}

Represents a primitive literal.

Named ‘Constant’ here for backwards compatibility.

This is similar as the primitives supported in the well-known type google.protobuf.Value, but richer so it can represent CEL’s full range of primitives.

Lists and structs are not included as constants as these aggregate types may contain [Expr][google.api.expr.v1alpha1.Expr] elements which require evaluation and are thus not constant.

Examples of literals include: "hello", b'bytes', 1u, 4.2, -2, true, null.

Fields

constant_kind: Option<ConstantKind>

Required. The valid constant kinds.

Trait Implementations

impl Clone for Constant

fn clone(&self) -> Constant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Constant

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

Formats the value using the given formatter.

impl Default for Constant

fn default() -> Constant

Returns the “default value” for a type.

impl Message for Constant

fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,
    ctx: DecodeContext
) -> Result<(), DecodeError> where
    B: Buf, 

fn encoded_len(&self) -> usize

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

fn clear(&mut self)

Clears the message, resetting all fields to their default.

pub fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message to a buffer.

pub fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message with a length-delimiter to a buffer.

pub fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes an instance of the message from a buffer.

pub fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes a length-delimited instance of the message from the buffer.

pub fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

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

pub fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq<Constant> for Constant

fn eq(&self, other: &Constant) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
