Struct Error

pub struct Error { /* private fields */ }

Implementations

impl Error

pub fn new(kind: ErrorKind, position: usize) -> Error

Constructs a new error with the error kind and the position.

Arguments

kind - The value of the error. Maintaining the value allows for the messages to be controlled across execution. position - The position where the error occurred.

pub fn message_only(kind: ErrorKind) -> Error

Constructs a new error with the error kind and no position.

Arguments

kind - The value of the error. Maintaining the value allows for the messages to be controlled across execution.

pub fn prettify(self, input: &str) -> String

This function generates a pretty version of the error, with arrows pointing to the exact location of the error. This function also consumes the error, therefore, it should be the last thing called.

Arguments

input - The input for the program. This is not maintained with every error because the input might be different.
