Struct ProtocolVersionsCache 

pub struct ProtocolVersionsCache {
    pub global_cache: IntMap<ProtocolVersion, u64>,
    /* private fields */
}

ProtocolVersion cache that handles both global and block data

Fields

global_cache: IntMap<ProtocolVersion, u64>

The current global cache for protocol versions

Implementations

impl ProtocolVersionsCache

pub fn new() -> Self

Create a new ProtocolVersionsCache instance

pub fn load_if_needed( &mut self, drive: &Drive, transaction: TransactionArg<'_, '_>, drive_version: &DriveVersion, ) -> Result<(), Error>

Load the protocol versions cache from disk if needed

pub fn set_block_cache_version_count( &mut self, version: ProtocolVersion, count: u64, )

Sets the protocol version to the block cache

pub fn get(&self, version: &ProtocolVersion) -> Result<Option<&u64>, Error>

Tries to get a version from block cache if present if block cache doesn’t have the version set then it tries get the version from global cache

pub fn block_global_cache(&mut self)

Disable the global cache to do not allow get counters If global cache is blocked then [get] will return an error

pub fn unblock_global_cache(&mut self)

Unblock the global cache This function enables the normal behaviour of [get] function

pub fn merge_block_cache(&mut self)

Merge block cache to global cache

pub fn clear_global_cache(&mut self)

Clears the global cache

pub fn clear_block_cache(&mut self)

Clear block cache

pub fn versions_passing_threshold( &self, required_upgraded_hpmns: u64, ) -> Vec<ProtocolVersion>

Collect versions passing threshold

Trait Implementations

impl Default for ProtocolVersionsCache

fn default() -> ProtocolVersionsCache

Returns the “default value” for a type.
