Trait Implementations

impl Clone for LazyDataTokenRepr

fn clone(&self) -> LazyDataTokenRepr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LazyDataTokenRepr

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

Formats the value using the given formatter.

impl<D> From<&LazyDataToken<D>> for LazyDataTokenRepr

fn from(token: &LazyDataToken<D>) -> Self

Converts to this type from the input type.

impl<D> From<LazyDataToken<D>> for LazyDataTokenRepr

fn from(token: LazyDataToken<D>) -> Self

Converts to this type from the input type.

impl PartialEq for LazyDataTokenRepr

fn eq(&self, other: &LazyDataTokenRepr) -> 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.
