Function extract_context_safe 

pub fn extract_context_safe(
    source: &[u8],
    byte_start: usize,
    byte_end: usize,
    context_bytes: usize,
) -> Option<String>

Safely extract context lines from source bytes around a byte span

Similar to extract_symbol_content_safe, but extracts context around a span rather than the span itself. This is useful for extracting surrounding lines for better context in code intelligence tools.

Arguments

• source - Source file contents as bytes
• byte_start - Start byte offset of the span (inclusive)
• byte_end - End byte offset of the span (exclusive)
• context_bytes - Number of additional bytes to extract before and after

Returns

Some(String) with the extracted context, or None if extraction fails

Example

let source = "line1\nline2\nline3\nline4";
let context = extract_context_safe(source.as_bytes(), 7, 13, 5);
// Extracts around "line2" with 5 bytes of context
