This module provides lenses and traversals for working with vectors.

# Documentation

# Isomorphisms

vector :: Iso [a] [b] (Vector a) (Vector b) Source #

Convert a list to a `Vector`

(or back)

`>>>`

True`[1,2,3] ^. vector == Vector.fromList [1,2,3]`

`>>>`

[1,2,3]`[1,2,3] ^. vector % re vector`

`>>>`

True`Vector.fromList [0,8,15] ^. re vector % vector == Vector.fromList [0,8,15]`

forced :: Iso (Vector a) (Vector b) (Vector a) (Vector b) Source #

Convert a `Vector`

to a version that doesn't retain any extra
memory.

# Lenses

`sliced i n`

provides a `Lens`

that edits the `n`

elements starting at
index `i`

from a `Lens`

.

This is only a valid `Lens`

if you do not change the length of the resulting
`Vector`

.

Attempting to return a longer or shorter vector will result in violations of
the `Lens`

laws.

`>>>`

True`Vector.fromList [1..10] ^. sliced 2 5 == Vector.fromList [3,4,5,6,7]`

`>>>`

True`(Vector.fromList [1..10] & sliced 2 5 % mapped .~ 0) == Vector.fromList [1,2,0,0,0,0,0,8,9,10]`
