Crate encode_unicode
source ·Expand description
Miscellaneous UTF-8 and UTF-16 types and methods.
§Optional features:
-
#![no_std]
-mode: There are a few differences:Error
doesn’t exist, butdescription()
is made available as an inherent impl.Extend
/FromIterator
-implementations forString
/Vec<u8>
/Vec<u16>
are missing.- There is no
io
, soUtf8Iterator
andUtf8CharSplitter
doesn’t implementRead
.
This feature is enabled by setting
default-features=false
inCargo.toml
:encode_unicode = {version="0.3.4", default-features=false}
-
Integration with the ascii crate:
ConvertUtf8Char
andUtf16Char
to and from ascii::AsciiChar
.
The minimum supported version of Rust is 1.15, older versions might work now but can break with a minor update.
Modules§
- Errors returned by various conversion methods in this crate.
- Iterator types that you should rarely need to name
Structs§
- An unicode codepoint stored as UTF-8.
- Read or iterate over the bytes of the UTF-8 representation of a codepoint.
- An unicode codepoint stored as UTF-16.
- Iterate over the units of the UTF-16 representation of a codepoint.
Traits§
- Extension trait for
char
that adds methods for converting to and from UTF-8 or UTF-16. - Iterator methods that convert between
u8
s andUtf8Char
oru16
s andUtf16Char
- Methods for iterating over
u8
andu16
slices as UTF-8 or UTF-16 characters. - Adds
.utf8chars()
and.utf16chars()
iterator constructors to&str
. - Methods for working with
u8
s as UTF-8 bytes. - Methods for working with
u16
s as UTF-16 units.
Functions§
- Converts an iterator of
Utf8Char
(or&Utf8Char
) to an iterator ofu8
s.
Is equivalent to calling.flat_map()
on the original iterator, but the returned iterator is ~40% faster. - Converts an iterator of
Utf16Char
(or&Utf16Char
) to an iterator ofu16
s.
Is equivalent to calling.flat_map()
on the original iterator, but the returned iterator is about twice as fast.
