Implementations

impl ContractPackage

pub fn new(
    access_key: URef,
    versions: ContractVersions,
    disabled_versions: DisabledVersions,
    groups: Groups
) -> Self

Create new ContractPackage (with no versions) from given access key.

pub fn access_key(&self) -> URef

Get the access key for this contract.

pub fn groups_mut(&mut self) -> &mut Groups

Get the mutable group definitions for this contract.

pub fn groups(&self) -> &Groups

Get the group definitions for this contract.

pub fn add_group(&mut self, group: Group, urefs: BTreeSet<URef>)

Adds new group to this contract.

pub fn lookup_contract_hash(
    &self,
    contract_version_key: ContractVersionKey
) -> Option<&ContractHash>

Lookup the contract hash for a given contract version (if present)

pub fn is_version_enabled(
    &self,
    contract_version_key: ContractVersionKey
) -> bool

Checks if the given contract version exists and is available for use.

pub fn insert_contract_version(
    &mut self,
    protocol_version_major: ProtocolVersionMajor,
    contract_hash: ContractHash
) -> ContractVersionKey

Insert a new contract version; the next sequential version number will be issued.

pub fn disable_contract_version(
    &mut self,
    contract_hash: ContractHash
) -> Result<(), Error>

Disable the contract version corresponding to the given hash (if it exists).

pub fn versions(&self) -> &ContractVersions

Returns reference to all of this contract's versions.

pub fn enabled_versions(&self) -> ContractVersions

Returns all of this contract's enabled contract versions.

pub fn versions_mut(&mut self) -> &mut ContractVersions

Returns mutable reference to all of this contract's versions (enabled and disabled).

pub fn take_versions(self) -> ContractVersions

Consumes the object and returns all of this contract's versions (enabled and disabled).

pub fn disabled_versions(&self) -> &DisabledVersions

Returns all of this contract's disabled versions.

pub fn disabled_versions_mut(&mut self) -> &mut DisabledVersions

Returns mut reference to all of this contract's disabled versions.

pub fn remove_group(&mut self, group: &Group) -> bool

Removes a group from this contract (if it exists).

pub fn current_contract_version(&self) -> Option<ContractVersionKey>

Return the contract version key for the newest enabled contract version.

pub fn current_contract_hash(&self) -> Option<ContractHash>

Return the contract hash for the newest enabled contract version.

Trait Implementations

impl Clone for ContractPackage

fn clone(&self) -> ContractPackage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContractPackage

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

Formats the value using the given formatter.

impl Default for ContractPackage

fn default() -> ContractPackage

Returns the "default value" for a type.

impl Eq for ContractPackage

impl FromBytes for ContractPackage

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

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl PartialEq<ContractPackage> for ContractPackage

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl StructuralEq for ContractPackage

impl StructuralPartialEq for ContractPackage

impl ToBytes for ContractPackage

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error> where
    Self: Sized, 

Consumes self and serializes to a Vec<u8>.
