Trait Implementations§

impl Clone for MapKey

fn clone(&self) -> MapKey

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for MapKey

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

Formats the value using the given formatter. Read more

impl PartialEq for MapKey

fn eq(&self, other: &MapKey) -> bool

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

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 TryFrom<Pair<'_, Rule>> for MapKey

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(pair: Pair<'_, Rule>) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for MapKey

impl StructuralPartialEq for MapKey
