Methods

`impl AsciiChar`[src]

`pub fn from<C: ToAsciiChar>(ch: C) -> Result<Self, ToAsciiCharError>`[src]

Constructs an ASCII character from a u8, char or other character type.

Failure

Returns Err(()) if the character can't be ASCII encoded.

Example

let a = AsciiChar::from('g').unwrap();
assert_eq!(a.as_char(), 'g');

`pub unsafe fn from_unchecked<C: ToAsciiChar>(ch: C) -> Self`[src]

Constructs an ASCII character from a char or u8 without any checks.

`pub fn as_byte(self) -> u8`[src]

Converts an ASCII character into a u8.

`pub fn as_char(self) -> char`[src]

Converts an ASCII character into a char.

`pub fn is_alphabetic(self) -> bool`[src]

Check if the character is a letter (a-z, A-Z)

`pub fn is_digit(self) -> bool`[src]

Check if the character is a number (0-9)

`pub fn is_alphanumeric(self) -> bool`[src]

Check if the character is a letter or number

`pub fn is_blank(self) -> bool`[src]

Check if the character is a space or horizontal tab

`pub fn is_whitespace(self) -> bool`[src]

Check if the character is a ' ', '\t', '\n' or '\r'

`pub fn is_control(self) -> bool`[src]

Check if the character is a control character

Examples

use ascii::ToAsciiChar;
assert_eq!('\0'.to_ascii_char().unwrap().is_control(), true);
assert_eq!('n'.to_ascii_char().unwrap().is_control(), false);
assert_eq!(' '.to_ascii_char().unwrap().is_control(), false);
assert_eq!('\n'.to_ascii_char().unwrap().is_control(), true);

`pub fn is_graph(self) -> bool`[src]

Checks if the character is printable (except space)

Examples

use ascii::ToAsciiChar;
assert_eq!('n'.to_ascii_char().unwrap().is_graph(), true);
assert_eq!(' '.to_ascii_char().unwrap().is_graph(), false);
assert_eq!('\n'.to_ascii_char().unwrap().is_graph(), false);

`pub fn is_print(self) -> bool`[src]

Checks if the character is printable (including space)

Examples

use ascii::ToAsciiChar;
assert_eq!('n'.to_ascii_char().unwrap().is_print(), true);
assert_eq!(' '.to_ascii_char().unwrap().is_print(), true);
assert_eq!('\n'.to_ascii_char().unwrap().is_print(), false);

`pub fn is_lowercase(self) -> bool`[src]

Checks if the character is alphabetic and lowercase

Examples

use ascii::ToAsciiChar;
assert_eq!('a'.to_ascii_char().unwrap().is_lowercase(), true);
assert_eq!('A'.to_ascii_char().unwrap().is_lowercase(), false);
assert_eq!('@'.to_ascii_char().unwrap().is_lowercase(), false);

`pub fn is_uppercase(self) -> bool`[src]

Checks if the character is alphabetic and uppercase

Examples

use ascii::ToAsciiChar;
assert_eq!('A'.to_ascii_char().unwrap().is_uppercase(), true);
assert_eq!('a'.to_ascii_char().unwrap().is_uppercase(), false);
assert_eq!('@'.to_ascii_char().unwrap().is_uppercase(), false);

`pub fn is_punctuation(self) -> bool`[src]

Checks if the character is punctuation

Examples

use ascii::ToAsciiChar;
assert_eq!('n'.to_ascii_char().unwrap().is_punctuation(), false);
assert_eq!(' '.to_ascii_char().unwrap().is_punctuation(), false);
assert_eq!('_'.to_ascii_char().unwrap().is_punctuation(), true);
assert_eq!('~'.to_ascii_char().unwrap().is_punctuation(), true);

`pub fn is_hex(self) -> bool`[src]

Checks if the character is a valid hex digit

Examples

use ascii::ToAsciiChar;
assert_eq!('5'.to_ascii_char().unwrap().is_hex(), true);
assert_eq!('a'.to_ascii_char().unwrap().is_hex(), true);
assert_eq!('F'.to_ascii_char().unwrap().is_hex(), true);
assert_eq!('G'.to_ascii_char().unwrap().is_hex(), false);
assert_eq!(' '.to_ascii_char().unwrap().is_hex(), false);

`pub fn as_printable_char(self) -> char`[src]

Unicode has printable versions of the ASCII control codes, like '␛'.

This function is identical with .as_char() for all values .is_printable() returns true for, but replaces the control codes with those unicodes printable versions.

Examples

assert_eq!('\0'.to_ascii_char().unwrap().as_printable_char(), '␀');
assert_eq!('\n'.to_ascii_char().unwrap().as_printable_char(), '␊');
assert_eq!(' '.to_ascii_char().unwrap().as_printable_char(), ' ');
assert_eq!('p'.to_ascii_char().unwrap().as_printable_char(), 'p');
