Struct Int32Rules

pub struct Int32Rules {
    pub const: Option<i32>,
    pub in: Vec<i32>,
    pub not_in: Vec<i32>,
    pub example: Vec<i32>,
    pub less_than: Option<LessThan>,
    pub greater_than: Option<GreaterThan>,
}

Int32Rules describes the rules applied to int32 values. These rules may also be applied to the google.protobuf.Int32Value Well-Known-Type.

Fields

const: Option<i32>

const requires the field value to exactly match the specified value. If the field value doesn’t match, an error message is generated.

message MyInt32 {
   // value must equal 42
   int32 value = 1 \[(buf.validate.field).int32.const = 42\];
}

in: Vec<i32>

in requires the field value to be equal to one of the specified values. If the field value isn’t one of the specified values, an error message is generated.

message MyInt32 {
   // value must be in list \[1, 2, 3\]
   int32 value = 1 \[(buf.validate.field).int32 = { in: [1, 2, 3\] }];
}

not_in: Vec<i32>

not_in requires the field value to not be equal to any of the specified values. If the field value is one of the specified values, an error message is generated.

message MyInt32 {
   // value must not be in list \[1, 2, 3\]
   int32 value = 1 \[(buf.validate.field).int32 = { not_in: [1, 2, 3\] }];
}

example: Vec<i32>

example specifies values that the field may have. These values SHOULD conform to other rules. example values will not impact validation but may be used as helpful guidance on how to populate the given field.

message MyInt32 {
   int32 value = 1 [
     (buf.validate.field).int32.example = 1,
     (buf.validate.field).int32.example = -10
   ];
}

less_than: Option<LessThan>

greater_than: Option<GreaterThan>

Implementations

impl Int32Rules

pub fn const(&self) -> i32

Returns the value of const, or the default value if const is unset.

Trait Implementations

impl Clone for Int32Rules

fn clone(&self) -> Int32Rules

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Int32Rules

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

Formats the value using the given formatter.

impl Default for Int32Rules

fn default() -> Self

Returns the “default value” for a type.

impl Message for Int32Rules

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 Int32Rules

fn eq(&self, other: &Int32Rules) -> 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.
