Struct Source 

pub(crate) struct Source<'a> {
    text: Option<Cow<'a, str>>,
    line_ending: LineEnding,
}

The current source of a document and the line ending to write.

Fields

text: Option<Cow<'a, str>>

line_ending: LineEnding

Implementations

impl<'a> Source<'a>

pub(crate) fn read( current: Option<&'a [u8]>, spec: LineEndingSpec, partial: bool, ) -> Result<Self, DocumentError>

Decode current and resolve the line ending of spec.

The bytes are only read when they can matter, which is under partial ownership or to preserve their line ending. The text is only kept under partial ownership, with its line endings changed to LF.

Errors

Returns an error for invalid UTF-8 and for a current source whose line endings cannot be resolved.

pub(crate) fn text(&self) -> Option<&str>

The current text with LF line endings, when it is kept.

pub(crate) fn write(&self, document: &impl Display) -> Vec<u8>

Render document with the resolved line ending.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
