HexStr<T>
A hex string. Has fields used in serializing whether to add a 0x to the encoding
and to make the hex value in capital letters or not.
Can be dereferenced to its value.
Fields§
§val: TValue of the hex string. Can be dereferenced
add_0x_with_encoding: boolFlag to add 0x when serializing the value
hex_in_caps: boolFlag to serialize the hex in capital letters
delimiter_after_nibble_count: usizeFlag to split every n amount of nibbles with a delimiter
delimiter: charSplit every n amount of nibbles with this delimiter
skip_last_0_values: boolSkip last 0 values. Whether or not to include 0 values

1.23.0 · sourcepub fn is_ascii(&self) -> bool
pub fn is_ascii(&self) -> bool
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());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)If the value of this byte is within the ASCII range, returns it as an
ASCII character. Otherwise, returns None.
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.

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.
