Trait Implementations

impl Debug for Expr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Expr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Expr

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'i> TryFrom<Pair<'i, Rule>> for Expr

type Error = ParserError

The type returned in the event of a conversion error.

fn try_from(value: Pair<'i, Rule>) -> Result<Self, Self::Error>

Performs the conversion.

impl<'i> TryFrom<Pair<'i, Rule>> for Expr

type Error = ParserError

The type returned in the event of a conversion error.

fn try_from(value: Pair<'i, Rule>) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Expr

impl StructuralPartialEq for Expr
