Trait Implementations

impl Debug for ConstraintError

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

Formats the value using the given formatter.

impl Display for ConstraintError

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

impl Error for ConstraintError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str
