Struct UpgradeTicket 

pub struct UpgradeTicket {
    pub cap: ID,
    pub package: ID,
    pub policy: u8,
    pub digest: MoveVec<u8>,
}

Permission to perform a particular upgrade (for a fixed version of the package, bytecode to upgrade with and transitive dependencies to depend against).

An UpgradeCap can only issue one ticket at a time, to prevent races between concurrent updates or a change in its upgrade policy after issuing a ticket, so the ticket is a “Hot Potato” to preserve forward progress.

Fields

cap: ID

(Immutable) ID of the UpgradeCap this originated from.

package: ID

(Immutable) ID of the package that can be upgraded.

policy: u8

(Immutable) The policy regarding what kind of upgrade this ticket permits.

digest: MoveVec<u8>

(Immutable) SHA256 digest of the bytecode and transitive dependencies that will be used in the upgrade.

Implementations

Trait Implementations

impl Clone for UpgradeTicket

fn clone(&self) -> UpgradeTicket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UpgradeTicket

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UpgradeTicket

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for UpgradeTicket

impl MoveStruct for UpgradeTicket

type StructTag = UpgradeTicketTypeTag

impl MoveType for UpgradeTicket

type TypeTag = UpgradeTicketTypeTag

fn from_bcs(bytes: &[u8]) -> Result<Self, Error>

Deserialize the contents of the Move type from BCS bytes.
