rustHow to define error type in Rust

Error types in Rust are defined using the enum keyword. An example of defining an error type is shown below:

enum ErrorType {
    FileError,
    NetworkError,
    ParseError,
}

This code defines an ErrorType enum with three variants: FileError, NetworkError, and ParseError.

Explanation:

• enum: keyword used to define an enum type
• ErrorType: name of the enum type
• FileError, NetworkError, ParseError: variants of the enum type, each representing a different type of error
