Struct casper_types::account::Account

pub struct Account { /* private fields */ }

Represents an Account in the global state.

Implementations

impl Account

pub fn new( account_hash: AccountHash, named_keys: NamedKeys, main_purse: URef, associated_keys: AssociatedKeys, action_thresholds: ActionThresholds ) -> Self

Creates a new account.

pub fn create( account: AccountHash, named_keys: NamedKeys, main_purse: URef ) -> Self

An Account constructor with presets for associated_keys and action_thresholds.

An account created with this method is valid and can be used as the target of a transaction. It will be created with an AssociatedKeys with a Weight of 1, and a default ActionThresholds.

pub fn extract_access_rights(&self) -> ContextAccessRights

Extracts the access rights from the named keys and main purse of the account.

pub fn named_keys_append(&mut self, keys: &mut NamedKeys)

Appends named keys to an account’s named_keys field.

pub fn named_keys(&self) -> &NamedKeys

Returns named keys.

pub fn named_keys_mut(&mut self) -> &mut NamedKeys

Returns a mutable reference to named keys.

pub fn account_hash(&self) -> AccountHash

Returns account hash.

pub fn main_purse(&self) -> URef

Returns main purse.

pub fn main_purse_add_only(&self) -> URef

Returns an AccessRights::ADD-only version of the main purse’s URef.

pub fn associated_keys(&self) -> &AssociatedKeys

Returns associated keys.

pub fn action_thresholds(&self) -> &ActionThresholds

Returns action thresholds.

pub fn add_associated_key( &mut self, account_hash: AccountHash, weight: Weight ) -> Result<(), AddKeyFailure>

Adds an associated key to an account.

pub fn remove_associated_key( &mut self, account_hash: AccountHash ) -> Result<(), RemoveKeyFailure>

Removes an associated key from an account.

Verifies that removing the key will not cause the remaining weight to fall below any action thresholds.

pub fn update_associated_key( &mut self, account_hash: AccountHash, weight: Weight ) -> Result<(), UpdateKeyFailure>

Updates an associated key.

Returns an error if the update would result in a violation of the key management thresholds.

pub fn set_action_threshold( &mut self, action_type: ActionType, weight: Weight ) -> Result<(), SetThresholdFailure>

Sets new action threshold for a given action type for the account.

Returns an error if the new action threshold weight is greater than the total weight of the account’s associated keys.

pub fn can_set_threshold( &self, new_threshold: Weight ) -> Result<(), SetThresholdFailure>

Verifies if user can set action threshold.

pub fn can_authorize(&self, authorization_keys: &BTreeSet<AccountHash>) -> bool

Checks whether all authorization keys are associated with this account.

pub fn can_deploy_with( &self, authorization_keys: &BTreeSet<AccountHash> ) -> bool

Checks whether the sum of the weights of all authorization keys is greater or equal to deploy threshold.

pub fn can_manage_keys_with( &self, authorization_keys: &BTreeSet<AccountHash> ) -> bool

Checks whether the sum of the weights of all authorization keys is greater or equal to key management threshold.

Trait Implementations

impl Clone for Account

fn clone(&self) -> Account

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Account

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

Formats the value using the given formatter.

impl From<Account> for StoredValue

fn from(value: Account) -> StoredValue

Converts to this type from the input type.

impl FromBytes for Account

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<Account> for Account

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

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

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

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

impl Serialize for Account

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

Serialize this value into the given Serde serializer.

impl ToBytes for Account

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 write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

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

Consumes self and serializes to a Vec<u8>.

impl TryFrom<StoredValue> for Account

type Error = TypeMismatch

The type returned in the event of a conversion error.

fn try_from(stored_value: StoredValue) -> Result<Self, Self::Error>

Performs the conversion.
