Struct Line 

pub struct Line {
    pub offset: usize,
    pub byte_offset: usize,
    pub len: u32,
    pub byte_len: u32,
    pub newline: u32,
}

Information about a line in source code.

This structure describes a line’s position and length in both character and byte offsets, which is important for proper UTF-8 handling.

Returned by Source trait methods to provide line metadata.

Fields

offset: usize

Character offset from the start of the source (0-based)

byte_offset: usize

Byte offset from the start of the source (0-based)

len: u32

Line length in characters (excluding newline)

byte_len: u32

Line length in bytes (excluding newline)

newline: u32

Newline sequence length in bytes (0, 1 for \n, 2 for \r\n)
