Struct solana_program::sysvar::recent_blockhashes::RecentBlockhashes

#[repr(C)]
pub struct RecentBlockhashes(_);

Contains recent block hashes and fee calculators.

The entries are ordered by descending block height, so the first entry holds the most recent block hash, and the last entry holds an old block hash.
