Macro split_ascii_whitespace 

macro_rules! split_ascii_whitespace {
    ($s: expr) => { ... };
}

Returns an array of substrings of a string slice, separated by ASCII whitespace.

ASCII whitespace characters are: space ( ), tab (\t), newline (\n), carriage return (\r), and form feed (\f).

Consecutive whitespace characters are treated as a single separator. Leading and trailing whitespace is ignored.

This macro is const-context only.

Examples

const TEXT: &str = "  hello   world  ";
const WORDS_ARRAY: [&str; 2] = const_str::split_ascii_whitespace!(TEXT);
const WORDS_SLICE: &[&str] = &const_str::split_ascii_whitespace!(TEXT);

assert_eq!(WORDS_ARRAY, WORDS_SLICE);
assert_eq!(WORDS_SLICE, &["hello", "world"]);

const TEXT: &str = "word1\t\tword2\n\nword3";
const WORDS: &[&str] = &const_str::split_ascii_whitespace!(TEXT);
assert_eq!(WORDS, &["word1", "word2", "word3"]);
