Methods from Deref<Target = u8>
pub fn is_ascii(&self) -> bool
1.23.0[src]
Checks if the value is within the ASCII range.
Examples
let ascii = 97u8; let non_ascii = 150u8; assert!(ascii.is_ascii()); assert!(!non_ascii.is_ascii());
pub fn to_ascii_uppercase(&self) -> u8
1.23.0[src]
Makes a copy of the value in its ASCII upper case equivalent.
ASCII letters 'a' to 'z' are mapped to 'A' to 'Z', but non-ASCII letters are unchanged.
To uppercase the value in-place, use make_ascii_uppercase
.
Examples
let lowercase_a = 97u8; assert_eq!(65, lowercase_a.to_ascii_uppercase());
pub fn to_ascii_lowercase(&self) -> u8
1.23.0[src]
Makes a copy of the value in its ASCII lower case equivalent.
ASCII letters 'A' to 'Z' are mapped to 'a' to 'z', but non-ASCII letters are unchanged.
To lowercase the value in-place, use make_ascii_lowercase
.
Examples
let uppercase_a = 65u8; assert_eq!(97, uppercase_a.to_ascii_lowercase());
pub fn eq_ignore_ascii_case(&self, other: &u8) -> bool
1.23.0[src]
Checks that two values are an ASCII case-insensitive match.
This is equivalent to to_ascii_lowercase(a) == to_ascii_lowercase(b)
.
Examples
let lowercase_a = 97u8; let uppercase_a = 65u8; assert!(lowercase_a.eq_ignore_ascii_case(&uppercase_a));
pub fn make_ascii_uppercase(&mut self)
1.23.0[src]
Converts this value to its ASCII upper case equivalent in-place.
ASCII letters 'a' to 'z' are mapped to 'A' to 'Z', but non-ASCII letters are unchanged.
To return a new uppercased value without modifying the existing one, use
to_ascii_uppercase
.
Examples
let mut byte = b'a'; byte.make_ascii_uppercase(); assert_eq!(b'A', byte);
pub fn make_ascii_lowercase(&mut self)
1.23.0[src]
Converts this value to its ASCII lower case equivalent in-place.
ASCII letters 'A' to 'Z' are mapped to 'a' to 'z', but non-ASCII letters are unchanged.
To return a new lowercased value without modifying the existing one, use
to_ascii_lowercase
.
Examples
let mut byte = b'A'; byte.make_ascii_lowercase(); assert_eq!(b'a', byte);

pub fn is_ascii_whitespace(&self) -> bool
1.24.0[src]
Checks if the value is an ASCII whitespace character: U+0020 SPACE, U+0009 HORIZONTAL TAB, U+000A LINE FEED, U+000C FORM FEED, or U+000D CARRIAGE RETURN.
Rust uses the WhatWG Infra Standard's definition of ASCII whitespace. There are several other definitions in wide use. For instance, the POSIX locale includes U+000B VERTICAL TAB as well as all the above characters, but—from the very same specification—the default rule for "field splitting" in the Bourne shell considers only SPACE, HORIZONTAL TAB, and LINE FEED as whitespace.
If you are writing a program that will process an existing file format, check what that format's definition of whitespace is before using this function.
Examples
#![feature(ascii_ctype)] let uppercase_a = b'A'; let uppercase_g = b'G'; let a = b'a'; let g = b'g'; let zero = b'0'; let percent = b'%'; let space = b' '; let lf = b'\n'; let esc = 0x1b_u8; assert!(!uppercase_a.is_ascii_whitespace()); assert!(!uppercase_g.is_ascii_whitespace()); assert!(!a.is_ascii_whitespace()); assert!(!g.is_ascii_whitespace()); assert!(!zero.is_ascii_whitespace()); assert!(!percent.is_ascii_whitespace()); assert!(space.is_ascii_whitespace()); assert!(lf.is_ascii_whitespace()); assert!(!esc.is_ascii_whitespace());
pub fn is_ascii_control(&self) -> bool
1.24.0[src]
Checks if the value is an ASCII control character: U+0000 NUL ... U+001F UNIT SEPARATOR, or U+007F DELETE. Note that most ASCII whitespace characters are control characters, but SPACE is not.
Examples
#![feature(ascii_ctype)] let uppercase_a = b'A'; let uppercase_g = b'G'; let a = b'a'; let g = b'g'; let zero = b'0'; let percent = b'%'; let space = b' '; let lf = b'\n'; let esc = 0x1b_u8; assert!(!uppercase_a.is_ascii_control()); assert!(!uppercase_g.is_ascii_control()); assert!(!a.is_ascii_control()); assert!(!g.is_ascii_control()); assert!(!zero.is_ascii_control()); assert!(!percent.is_ascii_control()); assert!(!space.is_ascii_control()); assert!(lf.is_ascii_control()); assert!(esc.is_ascii_control());
