sanctum-macros

受 https://github.com/Ellipsis-Labs/ellipsis-macros 启发

编译时 Pubkey 常量生成

solana_program 应该是使用这些宏的 crate 中声明的依赖。

declare_program_keys!

// first arg = program ID
// second arg = list of static PDA names and their seeds.
//
// Rules from solana runtime:
// - Each seed can have a max length of 32 bytes.
// - Each PDA can have max 16 seeds.

create_with_seed!

使用 Pubkey::create_with_seed 创建一个 Pubkey。

// args: (base, seed, owner)

当与 system_instruction::create_account_with_seed() 一起使用时，将在 ID 处创建一个新的由 OWNER_ID 程序拥有的账户。 BASE_ID 必须是签署者。
