Expand description

A matrix allocator of a memory buffer that may contain R::to_usize() * C::to_usize() elements of type T.

An allocator is said to be: − static: if R and C both implement DimName. − dynamic: if either one (or both) of R or C is equal to Dynamic.

Every allocator must be both static and dynamic. Though not all implementations may share the same Buffer type.

Associated Types

The type of buffer this allocator can instanciate.

The type of buffer with uninitialized components this allocator can instanciate.

Required methods

Allocates a buffer with the given number of rows and columns without initializing its content.

Assumes a data buffer to be initialized.

Safety

The user must make sure that every single entry of the buffer has been initialized, or Undefined Behavior will immediately occur.

Allocates a buffer initialized with the content of the given iterator.
