nxt.container.traits

Traits used by containers.

TODO: add isUnorderedContainer and isUnorderedRange traits and used to forbid hash algorithms to operate on unordered containers (such as hybrid_hashmap and hybrid_hashmap) and their ranges.

Public Imports

nxt.gc_traits public import nxt.gc_traits;: Undocumented in source.

Members

Enums

isLvalueAssignable eponymoustemplate isLvalueAssignable(T, U = T): Is true iff a T can be a assigned from an U l-value.
shouldBePassedByValue eponymoustemplate shouldBePassedByValue(T): Is true iff T can and (for performance reasons) should be passed by value.

Functions

makeInitZeroArray T[] makeInitZeroArray(size_t length): Allocate an array of T-elements of length length using allocator.

Templates

ContainerElementType template ContainerElementType(ContainerType, ElementType): Undocumented in source.
hasElaborateDestructorNew template hasElaborateDestructorNew(S): Variant of hasElaborateDestructor that also checks for destructor when S is a class.
isRvalueAssignable template isRvalueAssignable(T, U = T): Is true iff a T can be a assigned from an U r-value Opposite to std.traits.isRvalueAssignable this correctly handles uncopyable types.
isSet template isSet(T): Is true iff T is a set like container.
isSetOf template isSetOf(T, E): Is true iff T is a set like container with elements of type E.

Variables

isAddress enum bool isAddress(T);: Is true iff T is a memory address (either a class or a pointer). TODO: Replace with __traits(isAddress, T) when it's added.
shouldMove enum bool shouldMove(T);: True if the last reference of a T in the scope of its lifetime should be passed by move instead of by copy either because
