Struct SegmentLine 

pub struct SegmentLine<'a> { /* private fields */ }

A line of segments.

Represents a single line of text that may contain multiple styled segments.

Implementations

impl<'a> SegmentLine<'a>

pub const fn new() -> Self

Create an empty line.

pub fn from_segments(segments: Vec<Segment<'a>>) -> Self

Create a line from a vector of segments.

pub fn from_segment(segment: Segment<'a>) -> Self

Create a line from a single segment.

pub fn is_empty(&self) -> bool

Check if the line is empty.

pub fn len(&self) -> usize

Get the number of segments.

pub fn cell_length(&self) -> usize

Get the total cell width of the line.

pub fn push(&mut self, segment: Segment<'a>)

Add a segment to the end of the line.

pub fn segments(&self) -> &[Segment<'a>]

Get the segments as a slice.

pub fn segments_mut(&mut self) -> &mut Vec<Segment<'a>>

Get mutable access to segments.

pub fn iter(&self) -> impl Iterator<Item = &Segment<'a>>

Iterate over segments.

pub fn split_at_cell(&self, cell_pos: usize) -> (Self, Self)

Split the line at a cell position.

Returns (left, right) where the split respects grapheme boundaries.

pub fn to_plain_text(&self) -> String

Concatenate plain text from all segments.

pub fn into_owned(self) -> SegmentLine<'static>

Convert all segments to owned (remove lifetime constraints).

Trait Implementations

impl<'a> Clone for SegmentLine<'a>

fn clone(&self) -> SegmentLine<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for SegmentLine<'a>

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

Formats the value using the given formatter.

impl<'a> Default for SegmentLine<'a>

fn default() -> SegmentLine<'a>

Returns the “default value” for a type.

impl<'a, 'b> IntoIterator for &'b SegmentLine<'a>

type Item = &'b Segment<'a>

The type of the elements being iterated over.

type IntoIter = Iter<'b, Segment<'a>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> IntoIterator for SegmentLine<'a>

type Item = Segment<'a>

The type of the elements being iterated over.

type IntoIter = IntoIter<Segment<'a>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> PartialEq for SegmentLine<'a>

fn eq(&self, other: &SegmentLine<'a>) -> 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.
