pub struct Crds {
    pub table: IndexMap<CrdsValueLabel, VersionedCrdsValue>,
}

Fields

table: IndexMap<CrdsValueLabel, VersionedCrdsValue>

Stores the map of labels and values

Methods

impl Crds

pub fn new_versioned(
    &self,
    local_timestamp: u64,
    value: CrdsValue
) -> VersionedCrdsValue

must be called atomically with insert_versioned

pub fn insert_versioned(
    &mut self,
    new_value: VersionedCrdsValue
) -> Result<Option<VersionedCrdsValue>, CrdsError>

insert the new value, returns the old value if insert succeeds

pub fn insert(
    &mut self,
    value: CrdsValue,
    local_timestamp: u64
) -> Result<Option<VersionedCrdsValue>, CrdsError>

pub fn lookup(&self, label: &CrdsValueLabel) -> Option<&CrdsValue>

pub fn lookup_versioned(
    &self,
    label: &CrdsValueLabel
) -> Option<&VersionedCrdsValue>

pub fn update_record_timestamp(&mut self, pubkey: &Pubkey, now: u64)

Update the timestamp's of all the labels that are assosciated with Pubkey

pub fn find_old_labels(
    &self,
    now: u64,
    timeouts: &HashMap<Pubkey, u64>
) -> Vec<CrdsValueLabel>

Find all the keys that are older or equal to the timeout.

• timeouts - Pubkey specific timeouts with Pubkey::default() as the default timeout.

pub fn remove(&mut self, key: &CrdsValueLabel)
