This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
Various linear data structures can be expensive to construct in a
repetitive fashion. For example, to append a single value to the end
of a list is O(n), and as such doing so repeatedly is recommended
against.
As such, to efficiently construct such structures we have the notion
of a builder. This can be used to more efficiently prepend and
append values, and at the end we "run" the builder to construct the
overall value.
This module provides an abstraction over various builders for specific
data structures. It also aims to minimise the number of functions
required to add various values to the builder by using a typeclass and
newtype wrappers.
To construct a value from it's builder:
Start with either mempty for an empty Builder, or if you
have an initial value use fromValue.
Add initial values to the front or back using prepend / <|
or append / |> respectively.
Once you've finished constructing your builder, create your
final value with build.
Note: all instances are defined for both strict and lazy
ByteString and Text values.
