Struct DiscoveryHooks 

pub struct DiscoveryHooks {
    pub on_slot_discovery: fn(slot_idx: usize, hash: u32),
    pub on_bucket_mark: fn(hash: u32),
    pub on_bucket_split: fn(label: &str, slot_idx: usize),
}

Discovery callbacks installed by an exploration backend.

Each field is a plain function pointer (defaults are no-ops). The accounting layer never knows what these do — coverage bitmaps and fork dispatch live entirely behind these pointers.

Fields

on_slot_discovery: fn(slot_idx: usize, hash: u32)

A slot assertion (bool Sometimes/Reachable first pass, numeric watermark improvement, or frontier advance) made a discovery. Receives the slot index and the message hash.

on_bucket_mark: fn(hash: u32)

An each-bucket assertion was hit (called on every invocation). Receives the bucket hash for coverage marking.

on_bucket_split: fn(label: &str, slot_idx: usize)

An each-bucket assertion made a first discovery or quality improvement. Receives the message label and a slot index.

Implementations

impl DiscoveryHooks

pub const NOOP: Self
