pub struct Position<'i> { /* fields omitted */ }
A cursor position in a &str
which provides useful methods to manually parse that string.
Creates a Position
at the start of a &str
.
let start = Position::from_start("");
assert_eq!(start.pos(), 0);
Returns the byte position of this Position
as a usize
.
let input = "ab";
let mut start = Position::from_start(input);
assert_eq!(start.pos(), 0);
Creates a Span
from two Position
s.
Panics if the positions come from different inputs.
let input = "ab";
let start = Position::from_start(input);
let span = start.span(&start.clone());
assert_eq!(span.start(), 0);
assert_eq!(span.end(), 0);
Returns the line and column number of this Position
.
enum Rule {}
let input = "\na";
let mut state: Box<pest::ParserState<Rule>> = pest::ParserState::new(input);
let mut result = state.match_string("\na");
assert!(result.is_ok());
assert_eq!(result.unwrap().position().line_col(), (2, 2));
Returns the entire line of the input that contains this Position
.
enum Rule {}
let input = "\na";
let mut state: Box<pest::ParserState<Rule>> = pest::ParserState::new(input);
let mut result = state.match_string("\na");
assert!(result.is_ok());
assert_eq!(result.unwrap().position().line_of(), "a");
