Table - Inlined
- List
Array - A list array that stores variable-length lists of elements, similar to
Vec<Vec<T>>. - List
Encoding - ListV
Table - Native
Value - NativeValue serves as a wrapper type to allow us to implement Hash and Eq on all primitive types.
- Null
Array - A array where all values are null.
- Null
Encoding - NullV
Table - Primitive
Array - A primitive array that stores native types in a contiguous buffer of memory, along with an optional validity child.
- Primitive
Encoding - PrimitiveV
Table - Ref
- Struct
Array - A struct array that stores multiple named fields as columns, similar to a database row.
- Struct
Encoding - StructV
Table - Temporal
Array - An array wrapper for primitive values that have an associated temporal meaning.
- VarBin
Array - VarBin

Table - VarBin
View Array - A variable-length binary view array that stores strings and binary data efficiently.

Functions§
- compatible_
storage_ type - True if
value_typecan represent every value of the typedtype. - compute_
is_ constant - Assumes any floating point has been cast into its bit representation for which != and !is_eq are the same Assumes there’s at least 1 value in the slice, which is an invariant of the entry level function.
- compute_
min_ max - Compute the min and max of VarBin like array.
- smallest_
storage_ type - Maps a decimal precision into the smallest type that can represent it.
- varbin_
scalar
