Enum Support 

pub enum Support {
    Native,
    Unsupported,
}

Whether a source applies one predicate itself.

Keeps an Unsupported variant because in-memory compensation for a filter or a search is sound: the engine over-fetches and narrows. Do not conflate this with DependencySupport, which has no such variant.

Variants

Native

The source applies this predicate itself.

Unsupported

The source ignores this predicate; the engine narrows the wider result.

Implementations

impl Support

pub fn is_native(self) -> bool

Whether the source applies the predicate itself.

Trait Implementations

impl Clone for Support

fn clone(&self) -> Support

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Support

impl Debug for Support

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Support

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Support

impl Hash for Support

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl JsonSchema for Support

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

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 inline_schema() -> bool

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
