[][src]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

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);
