# Bedrock 🪨
Bedrock is a C++20 STL alternative. Smaller, simpler, in many case faster. It's a hobby project, don't expect much more than an interesting implementation reference for things.
Currently Windows only. Supports MSVC and Clang. There are no concrete plans to support more platforms/compilers at this time.
## Containers and Views
```c++
Vector // Roughly equivalent to std::vector, with extra useful methods (Find, SwapErase, etc.)
Span // Roughly equivalent to std::span
String // Roughly equivalent to std::string
StringView // Roughly equivalent to std::string_view
HashMap // Dense open addressed (Robin Hood) hash map. Key-value pairs are stored contiguously.
HashSet // Same as HashMap, but without values.
```
## Allocators
All containers come in different allocator flavors:
```c++
TempVector // Allocates from a thread local arena. Falls back to the heap if it runs out.
FixedVector // Allocates from a fixed-size arena embedded in the container.
VMemVector // Allocates from a virtual memory arena embedded in the container. Can grow while keeping a stable address.
ArenaVector // Allocates from an externally provided arena.
```
## Tests
Write tests anywhere:
```c++
REGISTER_TEST("Span")
{
int values[] = { 1, 2, 3, 4, 5 };
Span test = values;
Span first_two = test.First(2);
TEST_TRUE(first_two.Size() == 2);
TEST_TRUE(first_two[0] == 1);
TEST_TRUE(first_two[1] == 2);
};
```
The run them with `gRunAllTests()`.
## Other
Mutex, Atomic, Thread, Semaphore.
Function, many Type Traits, a few Algorithms...
## Building
Compile every cpp file in Bedrock/. Define `ASSERTS_ENABLED` if you want asserts and tests. That's about it.
