Struct codepage_437::Cp437Error

pub struct Cp437Error {
    pub representable_up_to: usize,
}

Errors which can occur when attempting to interpret a string as a sequence of cp437 codepoints.

As such, the into_cp437 family of functions and functions make use of this error, for example.

Fields

representable_up_to: usize

Returns the index in the given string up to which valid cp437 was verified.

It is the maximum index such that input[..index].to_cp_437() would return Ok(_).

Examples

// some unrepresentable characters, in a &str
let word = "Eżektor";

// ToCp437::to_cp437() returns a Cp437Error
let error = word.to_cp437(&CP437_CONTROL).unwrap_err();

// the second character is unrepresentable here
assert_eq!(error.representable_up_to, 1);
