pub fn logos_i64_key_of_f64(f: f64) -> Option<i64>Expand description
Numeric-unified map key: a Float used to index an Int-keyed map matches
the Int key i iff the float is exactly i (integral and in i64 range) —
the compiled mirror of the interpreter’s 1 == 1.0 key coercion. A
non-integral float (1.5) matches no Int key.
