Trait ShellErrorExt

Extensions for interrogating ShellError values in tests.

Required Methods

fn into_inner(self) -> Result<ShellError>

Tries to convert into an inner value from a ShellError.

Useful if the error is expected to be a generic error that contains an inner error or a chained error that chained another error.

However, this function returns None

• if inner of ShellError::Generic is empty
• if sources of ShellError::ChainedError is empty
• the error is none of the above types

So make sure that a None value is not surprise.

fn into_labeled(self) -> Result<LabeledError>

Extract the LabeledError from ShellError::LabeledError, if it is one.

fn generic_error(self) -> Result<String>

Extract the error field from ShellError::Generic, if it is one.

fn generic_msg(self) -> Result<String>

Extract the message field from ShellError::Generic, if it is one.
