enum SnippetState {
    EndOfInput(String),
    LineEnd(String, usize),
    EndWithLineFeed(String, usize),
}
Expand description

Result of breaking a string so it fits in a line and the state it ended in. The state informs about what to do with the snippet and how to continue the breaking process.

Variants§

§

EndOfInput(String)

The input could not be broken and so rewriting the string is finished.

§

LineEnd(String, usize)

The input could be broken and the returned snippet should be ended with a [StringFormat::line_end]. The next snippet needs to be indented.

The returned string is the line to print out and the number is the length that got read in the text being rewritten. That length may be greater than the returned string if trailing whitespaces got trimmed.

§

EndWithLineFeed(String, usize)

The input could be broken but a newline is present that cannot be trimmed. The next snippet to be rewritten could use more width than what is specified by the given shape. For example with a multiline string, the next snippet does not need to be indented, allowing more characters to be fit within a line.

The returned string is the line to print out and the number is the length that got read in the text being rewritten.
