Struct rustfmt_nightly::string::StringFormat

pub(crate) struct StringFormat<'a> {
    pub(crate) opener: &'a str,
    pub(crate) closer: &'a str,
    pub(crate) line_start: &'a str,
    pub(crate) line_end: &'a str,
    pub(crate) shape: Shape,
    pub(crate) trim_end: bool,
    pub(crate) config: &'a Config,
}

Describes the layout of a piece of text.

Fields

opener: &'a str

The opening sequence of characters for the piece of text

closer: &'a str

The closing sequence of characters for the piece of text

line_start: &'a str

The opening sequence of characters for a line

line_end: &'a str

The closing sequence of characters for a line

shape: Shape

The allocated box to fit the text into

trim_end: bool

Trim trailing whitespaces

config: &'a Config

Implementations

impl<'a> StringFormat<'a>

pub(crate) fn new(shape: Shape, config: &'a Config) -> StringFormat<'a>

fn max_width_with_indent(&self) -> Option<usize>

Returns the maximum number of graphemes that is possible on a line while taking the indentation into account.

If we cannot put at least a single character per line, the rewrite won’t succeed.

fn max_width_without_indent(&self) -> Option<usize>

Like max_width_with_indent but the indentation is not subtracted. This allows to fit more graphemes from the string on a line when SnippetState::EndWithLineFeed.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
