nalgebra_types2

The types of dimension 2 (shapes with max(rows, cols) = 2, their core-trait impls, products, indexing, solve / permutation / Givens / LU-step / Householder impls); Point2, Translation2, Perm2, Rotation2, Reflection2 (with its constructors and accessors), GivensRotation.

Part of nalgebra-cairo, the Cairo port of the Rust nalgebra crate on fixed::Fixed (Q32.32), built for provable game physics, split per dimension (docs/SPLIT.md §18: a number in a crate name is exactly that dimension; the dimension of a rectangular shape is max(rows, columns)).

What it holds

  • base::matrix2, base::vector2, base::row_vector2, base::point2: the shapes with max(rows, columns) = 2 (Matrix2, Matrix1x2, Matrix2x1, Vector2, RowVector2), their core-trait impls, products, indexing and solve impls;
  • geometry::rotation2, geometry::reflection2, geometry::translation2: the Rotation2, Reflection2 (with its constructors and accessors) and Translation2 types; Point2;
  • linalg::lu, linalg::givens: Perm2, the permutation, LU-step, Householder impls and GivensRotation with its methods.

Upstream's module paths are kept: nalgebra_types2::<module path> is nalgebra::<module path> (docs/SPLIT.md §3.1). It depends on nalgebra_core and simba.

When to depend on it

It is pulled in by 27 declared closures, the cheapest being core_pivot (3.5 s / 1.04 GB, 15 s / 3 GB).

Depend on the types crates when you need the matrix / vector / point types and their operators, products and indexing, without the named methods (norm(), transpose(), inverse(): those are in the static crates). nalgebra_types2 is the dimension-2 step.

For upstream's whole API at upstream's paths, depend on the facade nalgebra, which re-exports every sub-crate at the 0.1.0 paths.

internal

The modules under internal (internal::base, internal::geometry, internal::linalg) hold items that are crate-private in nalgebra 0.1.0 and that the split had to make pub to share them across crates: no stability promise.
