Function offset_range_to_lsp_range

src/diagnostics/mod.rs:2065–2076

Build a diagnostic range from byte offsets, returning `None` if either offset is past the end of `content`. This thin wrapper around [`crate::util::byte_range_to_lsp_range`] adds a bounds check so that stale byte offsets (e.g. from a previous AST after an edit) are rejected instead of silently clamped to EOF.

(
    content: &str,
    start_byte: usize,
    end_byte: usize,
)

/// a bounds check so that stale byte offsets (e.g. from a previous AST
/// after an edit) are rejected instead of silently clamped to EOF.
pub(crate) fn offset_range_to_lsp_range(
    content: &str,
    start_byte: usize,
    end_byte: usize,
) -> Option<Range> {
    if start_byte > content.len() || end_byte > content.len() {
        return None;
    }
    Some(crate::util::byte_range_to_lsp_range(
        content, start_byte, end_byte,
    ))
}
