Struct utf8_io::Utf8Reader
source · pub struct Utf8Reader<Inner: Read> { /* private fields */ }
Expand description
A Read
implementation which translates from an input Read
producing
an arbitrary byte sequence into a valid UTF-8 sequence with invalid
sequences replaced by U+FFFD (REPLACEMENT CHARACTER) in the manner of
String::from_utf8_lossy
, where scalar value encodings never straddle
read
calls (callers can do str::from_utf8
and it will always
succeed).
