Crate ascii

source · [−]
Expand description

A library that provides ASCII-only string and character types, equivalent to the char, str and String types in the standard library.

Please refer to the readme file to learn about the different feature modes of this crate.

Minimum supported Rust version

The minimum Rust version for 1.1.* releases is 1.41.1. Later 1.y.0 releases might require newer Rust versions, but the three most recent stable releases at the time of publishing will always be supported.
For example this means that if the current stable Rust version is 1.70 when ascii 1.2.0 is released, then ascii 1.2.* will not require a newer Rust version than 1.68.

History

This package included the Ascii types that were removed from the Rust standard library by the 2014-12 reform of the std::ascii module. The API changed significantly since then.

Structs

AsAsciiStrError
Error that is returned when a sequence of u8 are not all ASCII.
AsciiStr
AsciiStr represents a byte or string slice that only contains ASCII characters.
AsciiString
A growable string stored as an ASCII encoded buffer.
Chars
A copying iterator over the characters of an AsciiStr.
CharsMut
A mutable iterator over the characters of an AsciiStr.
CharsRef
An immutable iterator over the characters of an AsciiStr.
FromAsciiError
A possible error value when converting an AsciiString from a byte vector or string. It wraps an AsAsciiStrError which you can get through the ascii_error() method.
ToAsciiCharError
Error returned by ToAsciiChar.

Enums

AsciiChar
An ASCII character. It wraps a u8, with the highest bit always zero.

Traits

AsAsciiStr
Convert slices of bytes or AsciiChar to AsciiStr.
AsMutAsciiStr
Convert mutable slices of bytes or AsciiChar to AsciiStr.
IntoAsciiString
Convert vectors into AsciiString.
ToAsciiChar
Convert char, u8 and other character types to AsciiChar.

Functions

caret_decode
Returns the control code represented by a caret notation letter, or None if the letter is not used in caret notation.
caret_encode
Terminals use caret notation to display some typed control codes, such as ^D for EOT and ^Z for SUB.
