There was a problem hiding this comment.
If you want to add these and have them work similarly to the program error in the Rust SDK, may as well just copy all the variants at https://github.com/anza-xyz/solana-sdk/blob/2d88eb491e52705ec73ee8204dc41d510c298909/program-error/src/lib.rs#L57, but that will require also setting the values individually, ie:
const ProgramError = enum(u64) {
InvalidArgument = 1 << 32,
InvalidInstructionData = 2 << 32,
};
And so on. That'll be a bit more conformant than this error type.
On the other hand, it's not a proper zig error, which makes me think we might want to omit this entirely, and allow processInstruction to return any error. What do you think?

Add pub fn declareEntrypoint(comptime process_instruction: processInstruction) void ; so we can just only write processInstruction
