Bruno BELANYI 93d255623b Use 'pcg64_fast' for RNG
All checks were successful
ci/woodpecker/push/check Pipeline was successful
Details 
This is a higher quality source of randomness than a XOR-shift
generator, while still being fast and easy to write.

All checks were successful

Making 'Move' lightweight sounds like a better idea now that I am
looking at it with fresh eyes...
 2024-04-05 22:41:24 +01:00
Bruno BELANYI adad4118ae Account for captures in 'ChessBoard::{,un}do_move' 
This is a silly thing to forget...

Bruno BELANYI a4aa4ae1e4 Make 'half_move_clock' a 'u32'
All checks were successful
ci/woodpecker/push/check Pipeline was successful
Details 
It *could* be set to a high value due to e.g: starting the engine in the
middle of a game.

Moving from a `u8` to a `u32` does not change the size of the type, so
let's just do that.

Use that opportunity to fix the comment about the number of
*half-moves* (it's 50 moves *per player*).

This makes more sense from a user's perspective.

Bruno BELANYI b9cc60be9c Use 'ChessBoardBuilder' in 'FromFen' 
This will allow taking this *out* of the module, now that we don't need
to reach into the internals of 'ChessBoard'.
 2024-04-01 22:47:59 +01:00
Bruno BELANYI 829362dbce Add 'From<InvalidError>' for 'FenError' 2024-04-01 22:47:59 +01:00
Bruno BELANYI a676094dc1 Use 'ChessBoardBuilder' in validation tests 
The various tests for overlapping can't be triggered with the builder
API, so those have stayed unchanged.

Bruno BELANYI 8173fa2ccd Fix 'ChessBoard' validation test 
It wasn't actually testing the right thing due to the typo...
