Function extension_limit

hail-fuzz/src/extension.rs:410–417

Determine the maximum size of a single extension to try. The idea is to try small extensions first to avoid inputs becoming too large. This number increases the longer it takes to find new inputs.

(fuzzer: &Fuzzer)

/// first to avoid inputs becoming too large. This number increases the longer it takes to find
/// new inputs.
fn extension_limit(fuzzer: &Fuzzer) -> usize {
    let max_find_gap =
        fuzzer.input_id.map(|id| fuzzer.corpus[id].metadata.max_find_gap).unwrap_or(0);
    if max_find_gap < 0x1000 {
        return 32;
    }
    max_find_gap.next_power_of_two().min(0x10000) as usize
}
