Struct PositionBuilder 

pub struct PositionBuilder { /* private fields */ }

Builder for creating document positions with fluent API

Provides ergonomic ways to create positions:

use ass_editor::{EditorDocument, PositionBuilder};

let document = EditorDocument::from_content("Line 1\nLine 2\nLine 3").unwrap();

// PositionBuilder requires a Rope, not EditorDocument
// For this example, we'll use Position::new directly
let pos = ass_editor::Position::new(7); // Position at start of "Line 2"
     
assert_eq!(pos.offset, 7);

Implementations

impl PositionBuilder

pub const fn new() -> Self

Create a new position builder

pub const fn line(self, line: usize) -> Self

Set line number (1-indexed)

pub const fn column(self, column: usize) -> Self

Set column number (1-indexed)

pub const fn offset(self, offset: usize) -> Self

Set byte offset directly

pub const fn at_line_start(self, line: usize) -> Self

Build position at the start of a line

pub const fn at_line_end(self, line: usize) -> Self

Build position at the end of a line

pub const fn at_start() -> Self

Build position at the start of the document

pub fn build(self, rope: &Rope) -> Result<Position>

Available on crate feature rope only.

Build position using rope for line/column conversion

If offset is provided, uses that directly. Otherwise converts from line/column using the rope.
