For more details, see the std::str module.

Modules

• converts 🔒

Structs

• Utf8ChunkExperimental
  An item returned by the Utf8Chunks iterator.
• Utf8ChunksExperimental
  An iterator used to decode a slice of mostly UTF-8 bytes to string slices (&str) and byte slices (&[u8]).
• Bytes
  An iterator over the bytes of a string slice.
• BytesIsNotEmpty 🔒
• CharEscapeDebugContinue 🔒
• CharEscapeDefault 🔒
• CharEscapeUnicode 🔒
• CharIndices
  An iterator over the chars of a string slice, and their positions.
• Chars
  An iterator over the chars of a string slice.
• EncodeUtf16
  An iterator of u16 over the string encoded as UTF-16.
• EscapeDebug
  The return type of str::escape_debug.
• EscapeDefault
  The return type of str::escape_default.
• EscapeUnicode
  The return type of str::escape_unicode.
• IsAsciiWhitespace 🔒
• IsNotEmpty 🔒
• IsWhitespace 🔒
• Lines
  An iterator over the lines of a string, as string slices.
• LinesAnyDeprecated
  Created with the method lines_any.
• LinesMap 🔒
  A nameable, cloneable fn type
• MatchIndices
  Created with the method match_indices.
• Matches
  Created with the method matches.
• ParseBoolError
  An error returned when parsing a bool using from_str 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.
• SplitAsciiWhitespace
  An iterator over the non-ASCII-whitespace substrings of a string, separated by any amount of ASCII whitespace.
• SplitInclusive
  An iterator over the substrings of a string, terminated by a substring matching to a predicate function Unlike Split, it contains the matched part as a terminator of the subslice.
• SplitN
  Created with the method splitn.
• SplitTerminator
  Created with the method split_terminator.
• SplitWhitespace
  An iterator over the non-whitespace substrings of a string, separated by any amount of whitespace.
• UnsafeBytesToStr 🔒
• Utf8Error
  Errors which can occur when attempting to interpret a sequence of u8 as a string.

Traits

• FromStr
  Parse a value from a string

Functions

• next_code_point^⚠Experimental
  Reads the next code point out of a byte iterator (assuming a UTF-8-like encoding).
• slice_error_fail 🔒
• slice_error_fail_ct 🔒
• slice_error_fail_rt 🔒
• utf8_char_widthExperimental
  Given a first byte, determines how many bytes are in this UTF-8 character.
• from_utf8
  Converts a slice of bytes to a string slice.
• from_utf8_mut
  Converts a mutable slice of bytes to a mutable string slice.
• from_utf8_unchecked^⚠
  Converts a slice of bytes to a string slice without checking that the string contains valid UTF-8.
• from_utf8_unchecked_mut^⚠
  Converts a slice of bytes to a string slice without checking that the string contains valid UTF-8; mutable version.
