Struct InternStats 

pub struct InternStats {
    pub calls: u64,
    pub cache_hits: u64,
    pub table_hits: u64,
    pub allocs: u64,
    pub long_bypass: u64,
    pub resizes: u64,
    pub probe_steps: u64,
}

Diagnostic counters surfaced by Interner::stats.

Fields

calls: u64

Total intern calls (every entry into the API).

cache_hits: u64

Calls served from the inline cache.

table_hits: u64

Calls that landed on an existing table entry (no allocation).

allocs: u64

Calls that allocated a new entry into the arena.

long_bypass: u64

Calls that bypassed the table because the string exceeded INTERN_LENGTH_LIMIT — counted as an alloc as well.

resizes: u64

Total resize events the table performed.

probe_steps: u64

Total probe steps walked across all intern calls. Divided by calls - cache_hits gives the average probe length, the canonical hash-table health metric.
