Struct LineRange 

pub struct LineRange { /* private fields */ }

Lines start to end of a file, 1-based and inclusive; end absent means to the end of the file.

Written "110-300", or "110-" to the end. Read leniently, as models and people write ranges: "110..300", "110–300", "L110-L300", "lines 110-300", "-300" (from the first line), "110" (that line alone), or a bare number. Validated: lines are numbered from 1, and a range cannot end before it starts.

Implementations

impl LineRange

pub const FORM: &'static str = "Write a range of lines as \"<from>-<to>\" \ (1-based, both included, e.g. \"110-300\"), or \"<from>-\" to read to \ the end of the file."

How a range is written, for error messages

pub const INVALID: &'static str = "Invalid arguments at `lines`: "

How a refused range opens, as the seed runner shows a malformed lines argument, so that every range error reads alike (0.105.0)

pub fn new(start: u64, end: Option<u64>) -> Result<Self, &'static str>

Lines start..=end (end absent: to the end), or why not

pub fn start(&self) -> u64

The first line, from 1

pub fn end(&self) -> Option<u64>

The last line, or None for the end of the file

pub fn span(&self, text: &str) -> Result<LineSpan, PastEnd>

The span of text this range covers. A line is what ends at a \n, or the text’s end; an end past the last line is the last line
