Struct RandomXVmCache

Source
pub struct RandomXVmCache {
    pub seeds: VecDeque<(usize, [u8; 32])>,

Expand description

The randomX VMs cache, keeps the VM needed to calculate the current block’s proof-of-work hash (if a VM is needed) and a couple more around this VM.

Fields§

§seeds: VecDeque<(usize, [u8; 32])>

The top RX_SEEDS_CACHED RX seeds.

§vms: HashMap<usize, Arc<RandomXVm>>

The VMs for seeds (if after hf 12, otherwise this will be empty).

§cached_vm: Option<([u8; 32], Arc<RandomXVm>)>

A single cached VM that was given to us from a part of Cuprate.

Implementations§

Source§

impl RandomXVmCache

Source

pub async fn init_from_chain_height<D: Database + Clone>( chain_height: usize, hf: &HardFork, database: D, ) -> Result<Self, ContextCacheError>

Source

pub fn add_vm(&mut self, vm: ([u8; 32], Arc<RandomXVm>))

Add a randomX VM to the cache, with the seed it was created with.

Source

pub async fn get_alt_vm<D: Database>( &self, height: usize, chain: Chain, database: D, ) -> Result<Arc<RandomXVm>, ContextCacheError>

Creates a RX VM for an alt chain, looking at the main chain RX VMs to see if we can use one of them first.

Source

pub async fn get_vms(&mut self) -> HashMap<usize, Arc<RandomXVm>>

Get the main-chain RandomX VMs.

Source

pub fn pop_blocks_main_chain(&mut self, new_height: usize)

Removes all the RandomX VMs above the new_height.

Source

pub fn new_block(&mut self, height: usize, hash: &[u8; 32])

hash is the block hash not the blocks proof-of-work hash.
