Struct Expression

pub struct Expression(/* private fields */);

Represents an expression used in conditions.

Implementations

impl Expression

pub fn new<T>(expr: T) -> Expression

where T: ToString,

Creates a new Expression from a string.

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl Default for Expression

fn default() -> Expression

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Expression

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<A> From<Context<A>> for Expression

fn from(value: Context<A>) -> Expression

Converts to this type from the input type.

impl PartialEq for Expression

fn eq(&self, other: &Expression) -> 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 Expression

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.

impl Eq for Expression

impl StructuralPartialEq for Expression
