Enum LibError 

#[non_exhaustive]
pub enum LibError {
    CLIValueError(&'static str, String),
    CLITypeError(&'static str, String),

LibError represents one of all possible error cases possible to occur in this library

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CLIValueError(&'static str, String)

A value error for a CLI argument, e.g. “–radix” receives a negative number; specified by (CLI argument name, error message)

CLITypeError(&'static str, String)

A value error for a CLI argument, e.g. “–radix” receives a floating point number; specified by (CLI argument name, error message)

ArgValueError(usize, String)

A value error for a positional argument, e.g. “repeat” receives a negative number as argument; specified by (zero-based argument ID, error message)

ArgTypeError(usize, String)

A value error for a positional argument, e.g. “repeat” receives a boolean as argument; specified by (zero-based argument ID, error message)

ArgumentCountError(Range, usize, Option<String>)

The number of arguments received does not match this function’s signature. Specified by (expected, actual) number of arguments and an optional error message.

UnknownOp(String)

The user-provided operation name is unknown; specified by the op name.

InvalidData(String)

Internal error, where generated data does not satisfy required format; specified by an error message.

IOError(String)

internal error related to I/O; specified by an error message.

LocaleError(String)

The locale is not properly set up. A common case is that the locale data file does not contain necessary data to run the requested operation; specified by an error message.
