Trait ShellErrorExt 

pub 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 TestErrorKind::NoInner

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

Also if multiple inner values are found a TestErrorKind::MultipleInner is returned.

fn into_labeled(self) -> Result<LabeledError>

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

fn into_chained_iter(self) -> Result<impl Iterator<Item = ShellError>>

Extract the iterator on the sources of the [ChainedError] from ShellError::ChainedError, it 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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
