Module `std.experimental.allocator.common`

Utility and ancillary artifacts of std.experimental.allocator. This module shouldn't be used directly; its functionality will be migrated into more appropriate parts of std.

Functions

Name	Description
`alignedReallocate(alloc, b, s, a)`	The default `alignedReallocate` function first attempts to use `expand`. If `Allocator.expand` is not defined or returns `false`, `alignedReallocate` allocates a new block of memory of appropriate size and copies data from the old block to the new block. Finally, if `Allocator` defines `deallocate`, `alignedReallocate` uses it to free the old memory block.
`forwardToMember(member, funs)`	Forwards each of the methods in `funs` (if defined) to `member`.
`goodAllocSize(a, n)`	The default good size allocation is deduced as `n` rounded up to the allocator's alignment.
`reallocate(a, b, s)`	The default `reallocate` function first attempts to use `expand`. If `Allocator.expand` is not defined or returns `false`, `reallocate` allocates a new block of memory of appropriate size and copies data from the old block to the new block. Finally, if `Allocator` defines `deallocate`, `reallocate` uses it to free the old memory block.

Manifest constants

Name	Type	Description
`chooseAtRuntime`		`chooseAtRuntime` is a compile-time constant of type `size_t` that several parameterized structures in this module recognize to mean deferral to runtime of the exact value. For example, `BitmappedBlock!(Allocator, 4096)` (described in detail below) defines a block allocator with block size of 4096 bytes, whereas `BitmappedBlock!(Allocator, chooseAtRuntime)` defines a block allocator that has a field storing the block size, initialized by the user.
`hasStaticallyKnownAlignment`		Returns `true` if the `Allocator` has the alignment known at compile time; otherwise it returns `false`.
`platformAlignment`		The alignment that is guaranteed to accommodate any D object allocation on the current platform.
`stateSize`		Returns the size in bytes of the state that needs to be allocated to hold an object of type `T`. `stateSize!T` is zero for `struct`s that are not nested and have no nonstatic member variables.
`unbounded`		`unbounded` is a compile-time constant of type `size_t` that several parameterized structures in this module recognize to mean "infinite" bounds for the parameter. For example, `Freelist` (described in detail below) accepts a `maxNodes` parameter limiting the number of freelist items. If `unbounded` is passed for `maxNodes`, then there is no limit and no checking for the number of nodes.
