Struct LineRange 

pub struct LineRange {
    pub start: u32,
    pub end: u32,
}

Half-open line range [start, end) in a document.

Line indices are 0-based. end == start means the range is empty (zero lines). The largest representable range covers u32::MAX - 1 lines, which is sufficient for files up to ~4 billion lines.

Fields

start: u32

end: u32

Implementations

impl LineRange

pub fn new(start: u32, end: u32) -> Self

Construct a new line range. Debug-asserts start <= end.

pub fn is_empty(self) -> bool

true if the range covers zero lines.

pub fn len(self) -> u32

Number of lines covered.
