[−][src]Enum flaggy::error::Error

pub enum Error {

Error represents the various errors which can come up while parsing command-line flags.

Variants

AddrParse(AddrParseError)

An error parsing an IP address.

Internal(Error)

An internal unrecoverable error, usually due to some underlying library.

InvalidArgument(Error)

Errors akin to EINVAL - essentially, an argument passed into a function was invalid in some way..

Io(Error)

An I/O error, generally encountered when interacting with the filesystem.

StringParse(ParseError)

An awkward hack; this error exists to use String's FromStr impl, but this operation won't actually ever fail.

Unknown(Error)

An error of an unknown type occurred. Generally this comes from some dependency or underlying library, in a case where it's difficult to tell exactly what kind of problem occurred.

Values(Error)

A flaggy_values error.
