Required Methods§

Source

fn debug_fmt(&self, layer: usize, buf: &mut Vec<String>)

Source

fn next(&self) -> Option<&dyn StackError>

Provided Methods§

Source

fn last(&self) -> &dyn StackError
where Self: Sized,

Source

fn transparent(&self) -> bool

Indicates whether this error is “transparent”, that it delegates its “display” and “source” to the underlying error. Could be useful when you are just wrapping some external error, AND can not or would not provide meaningful contextual info. For example, the DataFusionError.
