zmdcstl is a data structure and algorithm library that mimic c++ stl. Bugs, support requests, and feature requests are welcome. Below are comparisons results between c++ stl and zmdcstl: currently without fully optimised, in average zmdcstl slower by 10% than c++stl in some tests cases. in some other test cases, zmdcstl can be faster than c++stl. benchmark_vector: zmdcstlvec:0.000255ms, stdvec:0ms, ratio: inf PASS benchmark_vector_ctor: (1 ticks, 0.001 sec) zmdcstlvec:681.317ms, stdvec:964.43ms, ratio: 0.706445 PASS benchmark_vector_ctor_n: (2935 ticks, 2.935 sec) vec_ctor_n_v_non_pod:1008.4ms, stdvec_n_v_non_pod:994.384ms, ratio: 1.0141 vec_ctor_n_v_pod:57.88ms, stdvec_n_v_pod:52.2712ms, ratio: 1.1073 vec_ctor_n_v_ctype:4.77279ms, stdvec_n_v_ctype:6.27634ms, ratio: 0.760441 PASS benchmark_vector_ctor_n_v: (3524 ticks, 3.524 sec) zmdcstlvec:1227.39ms, stdvec:1196.01ms, ratio: 1.02624 PASS benchmark_vector_ctor_range: (7499 ticks, 7.499 sec) zmdcstlvec:1256.16ms, stdvec:1211.05ms, ratio: 1.03725 PASS benchmark_vector_ctor_range_n: (7812 ticks, 7.812 sec) cstl_vector_ctor_vector:1225.48ms, std_vector_ctor_vector:1229.65ms, ratio: 0.996611 PASS benchmark_vector_ctor_vector: (7857 ticks, 7.857 sec) zmdcstlvec:20.4933ms, stdvec:540.694ms, ratio: 0.0379018 PASS benchmark_vector_erase: (3640 ticks, 3.640 sec) cstlvec_swap_ctype:0.000511ms, stdvec_swap_ctype:0ms, ratio: inf PASS benchmark_vector_swap: (32 ticks, 0.032 sec) cstlvec_reserve_non_pod:634.302ms, stdvec_reserve_non_pod:1963.87ms, ratio: 0.322986 cstlvec_reserve_pod:92.4203ms, stdvec_reserve_pod:83.7403ms, ratio: 1.10365 cstlvec_reserve_ctype:8.57114ms, stdvec_reserve_ctype:8.10692ms, ratio: 1.05726 PASS benchmark_vector_reserve: (6465 ticks, 6.465 sec) 9 tests - 9 passed, 0 failed, 0 skipped (39770 ticks, 39.770 sec) Total: 11 tests (39771 ticks, 39.771 sec), 0 assertions Pass: 11, fail: 0, skip: 0.
