vector-builder-0.3.7.2: Vector builder
An API for efficient and convenient construction of vectors.
It provides the composable Builder
abstraction, which has instances of the Monoid
and Semigroup
classes.
- Usage
First you use the Builder
abstraction to specify the structure of the vector.
Then you execute the builder to actually produce the vector.
- Example
The following code shows how you can efficiently concatenate different datastructures into a single immutable vector:
import qualified Data.Vector as A import qualified VectorBuilder.Builder as B import qualified VectorBuilder.Vector as C myVector :: A.Vector a -> [a] -> a -> A.Vector a myVector vector list element = C.build builder where builder = B.vector vector <> B.foldable list <> B.singleton element
