Error that is returned when a sequence of u8 are not all ASCII.

Is used by As[Mut]AsciiStr and the from_ascii method on AsciiStr and AsciiString.

Implementations

impl AsAsciiStrError

pub fn valid_up_to(self) -> usize

Returns the index of the first non-ASCII byte.

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