Struct PredefinedRules 

pub struct PredefinedRules {
    pub cel: Vec<Rule>,
}

Available on crate feature protovalidate only.

PredefinedRules are custom rules that can be re-used with multiple fields.

Fields

cel: Vec<Rule>

cel is a repeated field used to represent a textual expression in the Common Expression Language (CEL) syntax. For more information, see our documentation.

message MyMessage {
   // The field `value` must be greater than 42.
   optional int32 value = 1 [(buf.validate.predefined).cel = {
     id: "my_message.value",
     message: "value must be greater than 42",
     expression: "this > 42",
   }];
}

Trait Implementations

impl Clone for PredefinedRules

fn clone(&self) -> PredefinedRules

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PredefinedRules

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

Formats the value using the given formatter.

impl Default for PredefinedRules

fn default() -> Self

Returns the “default value” for a type.

impl Message for PredefinedRules

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.

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

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

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

where Self: Sized,

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

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

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

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

impl PartialEq for PredefinedRules

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