Struct sep2_common::packages::primitives::Uint8
source · pub struct Uint8(pub u8);
Expand description
We purposefully don’t use type aliases, as our procedural macros cannot determine whether a type is a primitive using an alias to it This means types that are just primitive aliases cannot be used without these primitive newtypes. We require newtypes for non-standard integer types regardless. Unsigned integer, max inclusive 255 (2^8-1)

1.23.0 · sourcepub fn is_ascii(&self) -> bool
pub fn is_ascii(&self) -> bool

let non_ascii = 150u8;
assert!(ascii.is_ascii());
assert!(!non_ascii.is_ascii());
sourcepub fn as_ascii(&self) -> Option<AsciiChar>
🔬This is a nightly-only experimental API. (ascii_char
)
pub fn as_ascii(&self) -> Option<AsciiChar>
ascii_char

.
1.23.0 · sourcepub fn to_ascii_uppercase(&self) -> u8
pub fn to_ascii_uppercase(&self) -> u8
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());
1.23.0 · sourcepub fn to_ascii_lowercase(&self) -> u8
pub fn to_ascii_lowercase(&self) -> u8
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());
1.23.0 · sourcepub fn eq_ignore_ascii_case(&self, other: &u8) -> bool
pub fn eq_ignore_ascii_case(&self, other: &u8) -> bool
Checks that two values are an ASCII case-insensitive match.
This is equivalent to to_ascii_lowercase(a) == to_ascii_lowercase(b)

let lowercase_a = 97u8;
let uppercase_a = 65u8;
assert!(lowercase_a.eq_ignore_ascii_case(&uppercase_a));

1.24.0 · sourcepub fn is_ascii_whitespace(&self) -> bool
pub fn is_ascii_whitespace(&self) -> bool
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
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' ';

1.24.0 · sourcepub fn is_ascii_control(&self) -> bool
pub fn is_ascii_control(&self) -> bool
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
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' ';
