1) Default-constructor. Constructs a match result with no established result state (ready() != true).
2) Constructs a match result with no established result state (ready() != true) using a copy of
a as the allocator.3) Copy-constructor. Constructs a match result with a copy of
rhs.4) Move-constructor. Constructs a match result with the contents of
rhs using move semantics. rhs is in valid, but unspecified state after the call.Parameters
| a | - | allocator to use for all memory allocations of this container |
| rhs | - | another match_result to use as source to initialize the match_result with |
