Enum NumericKind 

pub enum NumericKind {
    Finite,
    NaN,
    PosInf,
    NegInf,
}

A row-cell value, including SQL NULL. Float uses f64; NaN compares non-equal to itself (PG behaviour) — PartialEq is derived so callers must opt into NaN-aware comparison if they need stronger guarantees.

v7.37.42-arena Phase 1: parameterised on 'arena so heap-bearing variants (Text/Json/Xml/Bytes/Vector/BitString.bytes) can borrow from a per-query bump arena (Cow::Borrowed(&'arena ...)). Persistent / catalog Values use Value<'static> (alias ValueOwned) with Cow::Owned(...). Phase 1 keeps Range/Multirange recursive Box<Value> at 'static (owned) — arena migration deferred to a later phase. Array-of-Option variants (TextArray etc.) also stay owned in Phase 1; their nested shape is awkward for the simple Cow lift and the SCALARSQ hot path doesn’t touch them. v7.38 (read01, T6) — the IEEE-style class of a NUMERIC value. Finite is the ordinary fixed-point case; the specials mirror PG’s 'NaN' / 'Infinity' / '-Infinity'. Derived PartialEq gives NaN == NaN — correct for NUMERIC (unlike float’s NaN ≠ NaN); the total order (-Inf < finite < +Inf < NaN) lives in the comparison paths, not in Ord.
