Enum Scalars 

pub enum Scalars {
    Bool(Vec<bool>),
    U8(Vec<u8>),
    U16(Vec<u16>),
    U32(Vec<u32>),
    U64(Vec<u64>),
    I8(Vec<i8>),
    I16(Vec<i16>),
    I32(Vec<i32>),
    I64(Vec<i64>),
    F32(Vec<f32>),
    F64(Vec<f64>),
}

A run of scalars held in its native Rust form.

Building a list<f32> of 1,536 elements as Value::List allocates 1,536 Value enums before a single byte is written — fine for a one-off conversion, wrong for a hot write path. This carries the values as they already are, and the encoder writes the whole run in one pass.

The output is byte-identical to the equivalent Value::List, so this is purely a cost choice and never a wire-format one.
