mat v1.1.0

This release simplifies custom materialization by unifying it around the Materialize[A] API.

Highlights

  • Explicit materialization is now provided through Materialize.fromValue.
  • Explicit Materialize[A] evidence takes precedence over built-in derivation at every level, including nested products, tuples, intersections and sums.
  • Precise output types remain available through Materialize.Aux[A, O].
  • Documentation now includes the explicit materialization API and migration guidance.
  • Compile-time benchmark execution has been streamlined.

Breaking changes

  • Removed the redundant CustomMaterialize[A] API.

Migration

Replace custom materialization:

given CustomMaterialize[SomeType]:
  type Out = SomeType
  def apply(): SomeType = value

with:

given Materialize[SomeType] =
  Materialize.fromValue(value)

For a more precise output type:

given Materialize.Aux[Int, 5] =
  Materialize.fromValue[Int, 5](5)

Materialize.fromValue accepts its argument by name, so the expression is evaluated each time the materialized evidence is applied.
