Implementations

impl ConcurrentMerkleTreeHeader

pub fn initialize( &mut self, max_depth: u32, max_buffer_size: u32, authority: &Pubkey, creation_slot: u64, )

pub fn initialize_batched( &mut self, max_depth: u32, max_buffer_size: u32, authority: &Pubkey, creation_slot: u64, )

Initializes the header with the given parameters and sets the is_batch_initialized flag to true.
