Integer Types

All integer types are stored in little-endian format:

Type	Rust Type	Storage	Min	Max
Int8	i8	1 byte	-128	127
Int16	i16	2 bytes	-32,768	32,767
Int32	i32	4 bytes	-2³¹	2³¹-1
Int64	i64	8 bytes	-2⁶³	2⁶³-1
Int128	i128	16 bytes	-2¹²⁷	2¹²⁷-1
UInt8	u8	1 byte	0	255
UInt16	u16	2 bytes	0	65,535
UInt32	u32	4 bytes	0	2³²-1
UInt64	u64	8 bytes	0	2⁶⁴-1
UInt128	u128	16 bytes	0	2¹²⁸-1

Floating-Point Types

IEEE 754 floating-point numbers, stored in little-endian:

• Float32 - Single precision (32-bit)
• Float64 - Double precision (64-bit)

Bool Type

Bool is an alias for UInt8 where 0 = false, 1 = true.

Structs

ColumnVector

Generic column for numeric types

Traits

FixedSize

Trait for types that can be read/written as fixed-size values (synchronous version for columns)
