1//! `Pubkey` is the standard Solana pubkey type.
2//!
3//! Previously this module defined a custom `Pubkey([u8; 32])` newtype so it
4//! could implement zero-copy traits. For the general SDK surface we re-export
5//! `solana_pubkey::Pubkey` directly.
6//!
7//! [`ZeroCopyPubkey`] is a `[u8; 32]` newtype that additionally implements the
8//! `zerocopy` and `bytemuck` traits. It is used only where a pubkey must be
9//! embedded in a zero-copy / `Pod` struct (e.g. on-chain account metadata),
10//! since `solana_pubkey::Pubkey` does not implement those traits.
