Crate columnar 

Types supporting flat / “columnar” layout for complex types.

The intent is to re-layout Vec<T> types into vectors of reduced complexity, repeatedly. One should be able to push and pop easily, but indexing will be more complicated because we likely won’t have a real T lying around to return as a reference. Instead, we will use Generic Associated Types (GATs) to provide alternate references.

Modules

adts

Abstract data types represented in columnar form.

boxed

Support for Box<T> where T: Columnar.

bytes

Logic related to the transformation to and from bytes.

chain_mod

Chain iterators, or iterators and an item. Iterators that might improve inlining, at the expense of not providing iterator maker traits.

common

Common traits and types that are re-used throughout the module.

lookback

Containers that can store either values, or offsets to prior values.

primitive

Types that prefer to be represented by Vec<T>.

roaring

Roaring bitmap (and similar) containers.

string

sums

Containers for enumerations (“sum types”) that store variants separately.

tuple

vector

Traits

Borrow

A type that can be borrowed into a preferred reference type.

Columnar

A type that can be represented in columnar form.

Container

A container that can hold C, and provide its preferred references through Borrow.

ContainerBytes

A container that can also be viewed as and reconstituted from bytes.

Type Aliases

BorrowedOf

The borrowed container type of columnar type T.

ContainerOf

The container type of columnar type T.

Ref

For a lifetime, the reference type of columnar type T.
