Struct hdk::prelude::action::ZomeId

[−]

pub struct ZomeId(pub u8);

Expand description

this id is an internal reference, which also serves as a canonical ordering for zome initialization. The value should be auto-generated from the Zome Bundle def

pub fn is_ascii(&self) -> bool

Checks if the value is within the ASCII range.

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.

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 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).

pub fn is_ascii_alphabetic(&self) -> bool

Checks if the value is an ASCII alphabetic character:

U+0041 ‘A’ ..= U+005A ‘Z’, or
U+0061 ‘a’ ..= U+007A ‘z’.

pub fn is_ascii_uppercase(&self) -> bool

Checks if the value is an ASCII uppercase character: U+0041 ‘A’ ..= U+005A ‘Z’.

pub fn is_ascii_lowercase(&self) -> bool

Checks if the value is an ASCII lowercase character: U+0061 ‘a’ ..= U+007A ‘z’.

pub fn is_ascii_alphanumeric(&self) -> bool

Checks if the value is an ASCII alphanumeric character:

U+0041 ‘A’ ..= U+005A ‘Z’, or
U+0061 ‘a’ ..= U+007A ‘z’, or
U+0030 ‘0’ ..= U+0039 ‘9’.

pub fn is_ascii_digit(&self) -> bool

Checks if the value is an ASCII decimal digit: U+0030 ‘0’ ..= U+0039 ‘9’.

pub fn is_ascii_hexdigit(&self) -> bool

Checks if the value is an ASCII hexadecimal digit:

U+0030 ‘0’ ..= U+0039 ‘9’, or
U+0041 ‘A’ ..= U+0046 ‘F’, or
U+0061 ‘a’ ..= U+0066 ‘f’.

pub fn is_ascii_punctuation(&self) -> bool

Checks if the value is an ASCII punctuation character:

U+0021 ..= U+002F ! " # $ % & ' ( ) * + , - . /, or
U+003A ..= U+0040 : ; < = > ? @, or
U+005B ..= U+0060 [ \ ] ^ _ `, or
U+007B ..= U+007E { | } ~

pub fn is_ascii_graphic(&self) -> bool

Checks if the value is an ASCII graphic character: U+0021 ‘!’ ..= U+007E ‘~’.

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' ';
let lf = b'\n';
let esc = b'\x1b';

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

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' ';
let lf = b'\n';
let esc = b'\x1b';

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());
