Struct MapRules

Source
pub struct MapRules {
    pub min_pairs: Option<u64>,
    pub max_pairs: Option<u64>,

Expand description

MapRules describe the constraints applied to map values

Fields§

§min_pairs: Option<u64>

MinPairs specifies that this field must have the specified number of KVs at a minimum

§max_pairs: Option<u64>

MaxPairs specifies that this field must have the specified number of KVs at a maximum

§no_sparse: Option<bool>

NoSparse specifies values in this field cannot be unset. This only applies to map’s with message value types.

§keys: Option<Box<FieldRules>>

Keys specifies the constraints to be applied to each key in the field.

§values: Option<Box<FieldRules>>

Values specifies the constraints to be applied to the value of each key in the field. Message values will still have their validations evaluated unless skip is specified here.

§ignore_empty: Option<bool>

IgnoreEmpty specifies that the validation rules of this field should be evaluated only if the field is not empty

impl Name for MapRules

Source§

const NAME: &'static str = "MapRules"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.
Source§

const PACKAGE: &'static str = "validate"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.
Source§

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.
Source§

fn type_url() -> String
