Struct textwrap::core::Word

[+] Show declaration

pub struct Word<'a> {
    pub word: &'a str,
    pub whitespace: &'a str,
    pub penalty: &'a str,
    // some fields omitted
}

[−] Expand description

A piece of wrappable text, including any trailing whitespace.

A Word is an example of a Fragment, so it has a width, trailing whitespace, and potentially a penalty item.

Fields

word: &'a str

[−] Expand description

Word content.

whitespace: &'a str

[−] Expand description

Whitespace to insert if the word does not fall at the end of a line.

penalty: &'a str

[−] Expand description

Penalty string to insert if the word falls at the end of a line.

Implementations

impl<'a> Word<'a>[−]

pub fn from(word: &str) -> Word<'_>[−]

Construct a Word from a string.

A trailing stretch of ' ' is automatically taken to be the whitespace part of the word.

pub fn break_apart<'b>(
    &'b self,
    line_width: usize
) -> impl Iterator<Item = Word<'a>> + 'b[−]

Break this word into smaller words with a width of at most line_width. The whitespace and penalty from this Word is added to the last piece.

Examples

use textwrap::core::Word;
assert_eq!(
    Word::from("Hello!  ").break_apart(3).collect::<Vec<_>>(),
    vec![Word::from("Hel"), Word::from("lo!  ")]
);
