Crate use_line 

use-line

Composable line-level text primitives for RustUse.

use-line provides small helpers for line counting, indentation, dedentation, and line-ending normalization. It stays explicit about logical lines and keeps the behavior predictable across LF, CRLF, and CR inputs.

Included primitives

• line_count
• non_empty_line_count
• trim_lines
• normalize_line_endings
• indent_lines
• dedent_lines
• lines_with_numbers

Example

use use_line::{dedent_lines, line_count, lines_with_numbers, LineEnding};

assert_eq!(line_count("alpha\nbeta\n"), 2);
assert_eq!(dedent_lines("    alpha\n      beta"), "alpha\n  beta");
assert_eq!(lines_with_numbers("alpha")[0].number.get(), 1);
assert_eq!(LineEnding::Crlf.as_str(), "\r\n");

Structs

Line

A numbered logical line.

LineNumber

A 1-based line number.

LineStats

Aggregate line counts derived from text.

Enums

LineEnding

Supported line-ending shapes.

Functions

dedent_lines

Removes the common indentation shared by non-empty lines.

indent_lines

Prefixes each logical line with the provided indent string.

line_count

Counts logical lines, ignoring a trailing empty line created only by a final line ending.

lines_with_numbers

Returns numbered logical lines.

non_empty_line_count

Counts logical lines whose trimmed content is not empty.

normalize_line_endings

Normalizes line endings to the requested target.

trim_lines

Trims each logical line independently and preserves the input line-ending style when possible.
