Fields

min_len: Option<u64>

Requires the length of the map be greater than or equal to the value provided.

max_len: Option<u64>

Requires the length of the map be less than or equal to the value provided.

len: Option<u64>

Requires the length of the map be equal to the value provided.

key: Option<MapKeyConstraints>

Apply a constraints to the keys in the list.

value: Option<PrimitiveConstraints>

Apply a constraints to the values in the list.

Implementations

impl MapConstraints

pub fn min_len(&self) -> u64

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

pub fn max_len(&self) -> u64

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

pub fn len(&self) -> u64

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

Trait Implementations

impl Clone for MapConstraints

fn clone(&self) -> MapConstraints

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MapConstraints

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

Formats the value using the given formatter.

impl Default for MapConstraints

fn default() -> Self

Returns the “default value” for a type.

impl Message for MapConstraints

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 MapConstraints

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