Struct DeadMansSwitch 

pub struct DeadMansSwitch {
    pub payload_commitment: PayloadCommitment,
    pub heartbeat: Heartbeat,
    pub trigger: TriggerRule,
    pub disposition: Disposition,
    pub fired_unix: Option<u64>,
}

A dead-man switch over one commons payload.

Fields

payload_commitment: PayloadCommitment

The dataset this governs (by commitment) — held by the friends (the commons storers).

heartbeat: Heartbeat

trigger: TriggerRule

disposition: Disposition

fired_unix: Option<u64>

When the switch fired (enacted), if it has.

Implementations

impl DeadMansSwitch

pub fn is_triggered( &self, attestations: &[PartyAttestation], now_unix: u64, ) -> bool

Is the switch currently triggerable — the gamified rule satisfied and not already fired?

pub fn principal_alive(&mut self, now_unix: u64)

The principal is alive — reset the liveness signal and un-fire a not-yet-enacted switch. This is the reversibility: a person showing up defeats a premature or malicious trigger.

pub fn enact( &mut self, attestations: &[PartyAttestation], now_unix: u64, ) -> Option<&Disposition>

Enact the switch if triggerable: record it fired and return the Disposition to apply (which the caller carries out — publishing the key / issuing credentials to the disposition parties). Returns None if the rule is not satisfied (or it already fired).

Trait Implementations

impl Clone for DeadMansSwitch

fn clone(&self) -> DeadMansSwitch

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeadMansSwitch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DeadMansSwitch

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DeadMansSwitch

fn eq(&self, other: &DeadMansSwitch) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DeadMansSwitch

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
