end_line: u32

Implementations

impl FragmentId

pub fn new(path: Arc<str>, start_line: u32, end_line: u32) -> Self

end_line < start_line is closed off here rather than at call sites.

line_count() is end - start + 1 on unsigned integers, so an inverted span panics in debug and wraps to ~4 billion in release — and it does so somewhere downstream, far from whoever built the span. That has been fixed twice at the call site (fragmentation, signatures) and QA.md lists it as a recurring pattern; the constructor is the only place it can stop recurring.

Debug builds fail loudly at the point of construction, where the bug actually is. Release builds clamp to a one-line span, which is wrong but bounded — an honest degradation instead of a nonsense length that silently consumes an entire token budget.
