Trait Implementations

impl Debug for TokenValue

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

Formats the value using the given formatter.

impl From<TokenValue> for ExpectedToken

fn from(token: TokenValue) -> Self

Converts to this type from the input type.

impl PartialEq for TokenValue

fn eq(&self, other: &TokenValue) -> 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 StructuralPartialEq for TokenValue
