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);
