Modules

pattern	[Unstable] The string Pattern API.
traits

Structs

Bytes	External iterator for a string's bytes. Use with the `std::iter` module.
CharIndices	Iterator for a string's characters and their byte offsets.
Chars	Iterator for the char (representing Unicode Scalar Values) of a string
Lines	Created with the method [`lines()`].
LinesAny	[Deprecated] Created with the method [`lines_any()`].
LinesAnyMap	A nameable, cloneable fn type
MatchIndices	Created with the method [`match_indices()`].
MatchIndicesInternal
Matches	Created with the method [`matches()`].
MatchesInternal
ParseBoolError	An error returned when parsing a `bool` from a string fails.
RMatchIndices	Created with the method [`rmatch_indices()`].
RMatches	Created with the method [`rmatches()`].
RSplit	Created with the method [`rsplit()`].
RSplitN	Created with the method [`rsplitn()`].
RSplitTerminator	Created with the method [`rsplit_terminator()`].
Split	Created with the method [`split()`].
CharRange	[Unstable] Struct that contains a `char` and the index of the first byte of the next `char` in a string. This can be used as a data structure for iterating over the UTF-8 bytes of a string.
SplitInternal
SplitN	Created with the method [`splitn()`].
SplitNInternal
SplitTerminator	Created with the method [`split_terminator()`].
Utf8Error	Errors which can occur when attempting to interpret a sequence of `u8` as a string.

Constants

CONT_MASK	Mask of the value bits of a continuation byte
NONASCII_MASK
TAG_CONT_U8	Value of the tag bits (tag mask is !CONT_MASK) of a continuation byte

Statics

UTF8_CHAR_WIDTH

Traits

FromStr	A trait to abstract the idea of creating a new instance of a type from a string.
StrExt	[Unstable] Methods for string slices

Functions

char_range_at_raw	Pluck a code point out of a UTF-8-like byte slice and return the index of the next code point.
cmp_slice	Bytewise slice comparison. NOTE: This uses the system's memcmp, which is currently dramatically faster than comparing each byte in a loop.
contains_nonascii	Return `true` if any byte in the word `x` is nonascii (>= 128).
eq_slice	Bytewise slice equality NOTE: This function is (ab)used in rustc::middle::trans::_match to compare &[u8] byte slices that are not necessarily valid UTF-8.
from_raw_parts_mut	Forms a str from a pointer and a length.
from_utf8	Converts a slice of bytes to a string slice.
from_utf8_unchecked	Converts a slice of bytes to a string slice without checking that the string contains valid UTF-8.
next_code_point	[Unstable] Reads the next code point out of a byte iterator (assuming a UTF-8-like encoding).
next_code_point_reverse	Reads the last code point out of a byte iterator (assuming a UTF-8-like encoding).
run_utf8_validation	Walk through `iter` checking that it's a valid UTF-8 sequence, returning `true` in that case, or, if it is invalid, `false` with `iter` reset such that it is pointing at the first byte in the invalid sequence.
slice_error_fail
unwrap_or_0
utf8_acc_cont_byte	Return the value of `ch` updated with continuation byte `byte`.
utf8_first_byte	Return the initial codepoint accumulator for the first byte. The first byte is special, only want bottom 5 bits for width 2, 4 bits for width 3, and 3 bits for width 4.
utf8_is_cont_byte	Checks whether the byte is a UTF-8 continuation byte (i.e. starts with the bits `10`).
