Enum DbValueKey 

pub enum DbValueKey {
    Null,
    Bool(bool),
    Int(i64),
    FloatBits(u64),
    Str(String),
    Bytes(Vec<u8>),
}

Hashable key derived from a &DbValue.

See the module docs for the normalization rationale.

Variants

Null

Bool(bool)

Int(i64)

I16/I32/I64 unified — the most common PK/FK type, zero allocation.

FloatBits(u64)

F32/F64 unified via to_bits() — correct hash semantics for NaN.

Str(String)

Bytes(Vec<u8>)
