Struct Line

pub struct Line {
    pub text: LineText,
    /* private fields */
}

Text data and metadata for a single line of text

Note that the internal field accessed by .tag() and .set_tag() is shared throughout the historical instances of the Line.

The main way to create, move around or clone Line instances is through PubLine. For this purpose PubLine implements From<&Line> and Line implements From. (Creating a PubLine from a Line is basically free, creating a Line from a PubLine includes some allocations but still cheap.) This is to ensure that the internal pointers that Line uses internally (sharing objects between historical states) aren’t pointing to somewhere they shouldn’t.

Fields

text: LineText

The text data for a given line

LineText ensures that the text data is valid for a single line and implements reference counted cloning, allowing easy re-use of the same data (through history, clipboard and even multiple identical lines (depending on how they are created)).

Implementations

impl Line

pub fn tag(&self) -> char

Get the current value of the tag field.

pub fn set_tag(&self, new: char)

Set the tag to given character

Note that this changes all historical states of this line.

Trait Implementations

impl Debug for Line

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

Formats the value using the given formatter.

impl From<&Line> for PubLine

fn from(l: &Line) -> Self

Converts to this type from the input type.

impl From<&PubLine> for Line

fn from(l: &PubLine) -> Self

Converts to this type from the input type.

impl PartialEq for Line

fn eq(&self, other: &Line) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&str> for Line

type Error = LineTextError

The type returned in the event of a conversion error.

fn try_from(t: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Line

impl StructuralPartialEq for Line
