Traits and types for UTF-8 I/O
Structs
An interactive UTF-8 stream, combining
Utf8Reader
and Utf8Writer
.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).A
Write
implementation which translates into an output Write
producing a valid UTF-8 sequence from an arbitrary byte sequence from an
arbitrary byte sequence. Attempts to write invalid encodings are reported
as errors.Traits
Extend the
Read
trait with read_str
, a method for reading UTF-8 data.Add a convenience and optimizing method for writing from
str
.Functions
Like
std::io::copy
, but for streams that can operate directly on strings,
so we can avoid re-validating them as UTF-8.Default implementation of
ReadStr::read_exact_str
.Default implementation of
Write::write_fmt
, in terms of
WriteStr::write_str
.Default implementation of
WriteStr::write_str
, in terms of
Write::write_all
.
