Struct EnumRules 

pub struct EnumRules {
    pub const: Option<i32>,
    pub defined_only: Option<bool>,
    pub in: Vec<i32>,
    pub not_in: Vec<i32>,
}

EnumRules describe the constraints applied to enum values

Fields

const: Option<i32>

Const specifies that this field must be exactly the specified value

defined_only: Option<bool>

DefinedOnly specifies that this field must be only one of the defined values for this enum, failing on any undefined value.

in: Vec<i32>

In specifies that this field must be equal to one of the specified values

not_in: Vec<i32>

NotIn specifies that this field cannot be equal to one of the specified values

Implementations

impl EnumRules

pub fn const(&self) -> i32

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

pub fn defined_only(&self) -> bool

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

Trait Implementations

impl Clone for EnumRules

fn clone(&self) -> EnumRules

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnumRules

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

Formats the value using the given formatter.

impl Default for EnumRules

fn default() -> Self

Returns the “default value” for a type.

impl Message for EnumRules

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 EnumRules

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

impl ReflectMessage for EnumRules

fn descriptor(&self) -> MessageDescriptor

Gets a MessageDescriptor describing the type of this message.

fn transcode_to_dynamic(&self) -> DynamicMessage

where Self: Sized,

Converts this message into an instance of DynamicMessage by going through the byte representation.
