Struct ascii::Ascii

pub struct Ascii {
    // some fields omitted
}

Datatype to hold one ascii character. It wraps a u8, with the highest bit always zero.

Methods

impl Ascii

fn from(ch: char) -> Result<Ascii, ()>

Constructs an Ascii character from a char.

Failure

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

Example

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

fn as_byte(&self) -> u8

Converts an ascii character into a u8.

fn as_char(&self) -> char

Converts an ascii character into a char.

fn is_alphabetic(&self) -> bool

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

fn is_digit(&self) -> bool

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

fn is_alphanumeric(&self) -> bool

Check if the character is a letter or number

fn is_blank(&self) -> bool

Check if the character is a space or horizontal tab

fn is_control(&self) -> bool

Check if the character is a control character

fn is_graph(&self) -> bool

Checks if the character is printable (except space)

fn is_print(&self) -> bool

Checks if the character is printable (including space)

fn is_lowercase(&self) -> bool

Checks if the character is alphabetic and lowercase

fn is_uppercase(&self) -> bool

Checks if the character is alphabetic and uppercase

fn is_punctuation(&self) -> bool

Checks if the character is punctuation

fn is_hex(&self) -> bool

Checks if the character is a valid hex digit
