# Function encoding_rs::mem::check_utf8_for_latin1_and_bidi [−] [src]

    pub fn check_utf8_for_latin1_and_bidi(buffer: &[u8]) -> Latin1Bidi

Checks whether a potentially invalid UTF-8 buffer contains code points that trigger right-to-left processing or is all-Latin1.

Possibly more efficient than performing the checks separately.

Returns `Latin1Bidi::Latin1` if `is_utf8_latin1()` would return `true`. Otherwise, returns `Latin1Bidi::Bidi` if `is_utf8_bidi()` would return `true`. Otherwise, returns `Latin1Bidi::LeftToRight`.
