Enum LiteralValue

pub enum LiteralValue {
    Dyn(DynLiteralValue),
    Scalar(Scalar),
    Series(SpecialEq<Series>),
    Range(RangeLiteralValue),
}

Variants

Dyn(DynLiteralValue)

Scalar(Scalar)

Series(SpecialEq<Series>)

Range(RangeLiteralValue)

Trait Implementations

impl Clone for LiteralValue

fn clone(&self) -> LiteralValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LiteralValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LiteralValue

fn deserialize<__D>( __deserializer: __D, ) -> Result<LiteralValue, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<AnyValue<'_>> for LiteralValue

fn from(value: AnyValue<'_>) -> LiteralValue

Converts to this type from the input type.

impl From<Scalar> for LiteralValue

fn from(value: Scalar) -> LiteralValue

Converts to this type from the input type.

impl Hash for LiteralValue

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

where H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Literal for LiteralValue

fn lit(self) -> Expr

Literal expression.

impl PartialEq for LiteralValue

fn eq(&self, other: &LiteralValue) -> 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 Serialize for LiteralValue

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
