Trait ArrayType 

pub trait ArrayType<T: ?Sized> {
    type Array<Buffer: BufferType, OffsetItem: Offset, UnionLayout: UnionType>: Array;
}

Types that can be stored in Arrow arrays.

Required Associated Types

type Array<Buffer: BufferType, OffsetItem: Offset, UnionLayout: UnionType>: Array

The Array type for these items.

It is generic over:

• Buffer: a BufferType that is used for the array.
• OffsetItem: an Offset that is used for arrays with offset buffers.
• UnionLayout: a UnionType that is used for union arrays.

When using this type constructor for arrays that have no offset buffer offset::NA should be used to indicate that this does not apply.

When using this type constructor to construct arrays that are not union arrays union::NA should be used to indicate that does not apply.

This still ends up setting the default type, but this is needed because there are no default types for generic associated types.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
