Description

Zero based arrays. Note that no bounds checking are performed.

Basic non-strict arrays. Note: The Data.Array.IArray module provides a more general interface to immutable arrays: it defines operations with the same names as those defined below, but with more general types, and also defines Array instances of the relevant classes. To use that more general interface, import Data.Array.IArray but not Data.Array.

The type of immutable non-strict (boxed) arrays with indices in i and elements in e.

Primitive arrays of boxed values.

Boxed arrays.

Provides TextShow instances for Array types, as well as the showbIArrayPrec function. Since: 2

A generic array decoder. Here's how you can use it to produce a specific array value decoder:

x :: Value [[Text]]
x = array (dimension replicateM (dimension replicateM (element (nonNullable text))))

Generic array encoder. Here's an example of its usage:

someParamsEncoder :: Params [[Int64]]
someParamsEncoder = param (nonNullable (array (dimension foldl' (dimension foldl' (element (nonNullable int8))))))

Please note that the PostgreSQL IN keyword does not accept an array, but rather a syntactical list of values, thus this encoder is not suited for that. Use a value = ANY($1) condition instead.
