impl From<ExistsError> for AddRouteError

fn from(_: ExistsError) -> AddRouteError

Converts to this type from the input type.

impl PartialEq for ExistsError

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

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.
