Trait Implementations

impl<'i, FeatureId: Clone> Clone for QueryFeature<'i, FeatureId>

fn clone(&self) -> QueryFeature<'i, FeatureId>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'i, FeatureId: Debug> Debug for QueryFeature<'i, FeatureId>

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

Formats the value using the given formatter.

impl<'de: 'i, 'i, FeatureId> Deserialize<'de> for QueryFeature<'i, FeatureId>

where FeatureId: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'any, 'i, FeatureId> IntoOwned<'any> for QueryFeature<'i, FeatureId>

where FeatureId: IntoOwned<'any>,

fn into_owned(self) -> Self::Owned

Consumes the value and returns an owned clone.

type Owned = QueryFeature<'any, <FeatureId as IntoOwned<'any>>::Owned>

A variant of Self with a new lifetime.

impl<'i, FeatureId: JsonSchema> JsonSchema for QueryFeature<'i, FeatureId>

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl<'i, FeatureId> Parse<'i> for QueryFeature<'i, FeatureId>

where FeatureId: for<'x> Parse<'x> + Debug + PartialEq + ValueType,

fn parse<'t>( input: &mut Parser<'i, 't>, ) -> Result<Self, ParseError<'i, ParserError<'i>>>

Parse a value of this type using an existing parser.

fn parse_string(input: &'i str) -> Result<Self, ParseError<'i, ParserError<'i>>>

Parse a value from a string.

impl<'i, FeatureId: PartialEq> PartialEq for QueryFeature<'i, FeatureId>

fn eq(&self, other: &QueryFeature<'i, FeatureId>) -> 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.

Available on crate feature visitor only.

Visit the children of this value.

fn visit(&mut self, visitor: &mut V) -> Result<(), V::Error>

Available on crate feature visitor only.

Visits the value by calling an appropriate method on the Visitor. If no corresponding visitor method exists, then the children are visited.
