🔬This is a nightly-only experimental API. (`ascii_char` #110998)
Expand description

One of the 128 Unicode characters from U+0000 through U+007F, often known as the ASCII subset.

Officially, this is the first block in Unicode, Basic Latin. For details, see the C0 Controls and Basic Latin code chart.

This block was based on older 7-bit character code standards such as ANSI X3.4-1977, ISO 646-1973, and NIST FIPS 1-2.

## §When to use this

The main advantage of this subset is that it’s always valid UTF-8. As such, the `&[ascii::Char]` -> `&str` conversion function (as well as other related ones) are O(1): no runtime checks are needed.

If you’re consuming strings, you should usually handle Unicode and thus accept `str`s, not limit yourself to `ascii::Char`s.

However, certain formats are intentionally designed to produce ASCII-only output in order to be 8-bit-clean. In those cases, it can be simpler and faster to generate `ascii::Char`s instead of dealing with the variable width properties of general UTF-8 encoded strings, while still allowing the result to be used freely with other Rust things that deal in general `str`s.

For example, a UUID library might offer a way to produce the string representation of a UUID as an `[ascii::Char; 36]` to avoid memory allocation yet still allow it to be used as UTF-8 via `as_str` without paying for validation (or needing `unsafe` code) the way it would if it were provided as a `[u8; 36]`.

## §Layout

This type is guaranteed to have a size and alignment of 1 byte.

## §Names

The variants on this type are Unicode names of the characters in upper camel case, with a few tweaks:

- For `<control>` characters, the primary alias name is used.
- `LATIN` is dropped, as this block has no non-latin letters.
- `LETTER` is dropped, as `CAPITAL`/`SMALL` suffices in this block.
- `DIGIT`s use a single digit rather than writing out `ZERO`, `ONE`, etc.

## Implementations§

Source§

### impl AsciiChar

Source

#### pub const fn from_u8(b: u8) -> Option<Self>

🔬This is a nightly-only experimental API. (`ascii_char` #110998)

Creates an ascii character from the byte `b`, or returns `None` if it’s too large.

Source

#### pub const unsafe fn from_u8_unchecked(b: u8) -> Self

🔬This is a nightly-only experimental API. (`ascii_char` #110998)

Creates an ASCII character from the byte `b`, without checking whether it’s valid.

##### §Safety

`b` must be in `0..=127`, or else this is UB.

Source

#### pub const fn digit(d: u8) -> Option<Self>

🔬This is a nightly-only experimental API. (`ascii_char` #110998)

When passed the number `0`, `1`, …, `9`, returns the character `'0'`, `'1'`, …, `'9'` respectively.

If `d >= 10`, returns `None`.

Source

#### pub const unsafe fn digit_unchecked(d: u8) -> Self

🔬This is a nightly-only experimental API. (`ascii_char` #110998)

When passed the number `0`, `1`, …, `9`, returns the character `'0'`, `'1'`, …, `'9'` respectively, without checking that it’s in-range.

##### §Safety

This is immediate UB if called with `d > 64`.

If `d >= 10` and `d <= 64`, this is allowed to return any value or panic. Notably, it should not be expected to return hex digits, or any other reasonable extension of the decimal digits.

(This loose safety condition is intended to simplify soundness proofs when writing code using this method, since the implementation doesn’t need something really specific, not to make those other arguments do something useful. It might be tightened before stabilization.)

Source

#### pub const fn to_u8(self) -> u8

🔬This is a nightly-only experimental API. (`ascii_char` #110998)

Gets this ASCII character as a byte.

Source

#### pub const fn to_char(self) -> char

🔬This is a nightly-only experimental API. (`ascii_char` #110998)

Gets this ASCII character as a `char` Unicode Scalar Value.

Source

#### pub const fn as_str(&self) -> &str

🔬This is a nightly-only experimental API. (`ascii_char` #110998)

Views this ASCII character as a one-code-unit UTF-8 `str`.
