Trait embedded_error_chain::ChainError

pub trait ChainError<O: ErrorCategory, Tag> {
    pub fn chain(self, error_code: O) -> Error<O>;
}

A trait that allows chaining of Error and DynError values and any value of a type that implements ErrorCategory.

Required methods

pub fn chain(self, error_code: O) -> Error<O>

Chain this error with the supplied error_code.

Panics

If the error category O is not linked with the ErrorCategory of the most recent error code, this function will panic.

impl<O: ErrorCategory> ChainError<O, DynError> for DynError

pub fn chain(self, error_code: O) -> Error<O>

Chain a DynError with any error code of a linked ErrorCategory.

Note that this function has complexity O(n) where n is the length of the slice returned by O::chainable_category_formatters().

Panics

A call to this function panics if the slice of ErrorCodeFormatters returned by O::chainable_category_formatters() does not contain self.formatter().
