Trait Implementations

impl Debug for TermError

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

Formats the value using the given formatter.

impl Display for TermError

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

Formats the value using the given formatter.

impl Error for TermError

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