Struct casper_types::account::associated_keys::AssociatedKeys

pub struct AssociatedKeys(/* private fields */);

A mapping that represents the association of a Weight with an AccountHash.

Implementations

impl AssociatedKeys

pub fn new(key: AccountHash, weight: Weight) -> AssociatedKeys

Constructs a new AssociatedKeys.

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

Adds new AssociatedKey to the set. Returns true if added successfully, false otherwise.

pub fn remove_key(&mut self, key: &AccountHash) -> Result<(), RemoveKeyFailure>

Removes key from the associated keys set. Returns true if value was found in the set prior to the removal, false otherwise.

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

Adds new AssociatedKey to the set. Returns true if added successfully, false otherwise.

pub fn get(&self, key: &AccountHash) -> Option<&Weight>

Returns the weight of an account hash.

pub fn contains_key(&self, key: &AccountHash) -> bool

Returns true if a given key exists.

pub fn iter(&self) -> impl Iterator<Item = (&AccountHash, &Weight)>

Returns an iterator over the account hash and the weights.

pub fn len(&self) -> usize

Returns the count of the associated keys.

pub fn is_empty(&self) -> bool

Returns true if the associated keys are empty.

pub fn calculate_keys_weight( &self, authorization_keys: &BTreeSet<AccountHash> ) -> Weight

Calculates total weight of authorization keys provided by an argument

pub fn total_keys_weight(&self) -> Weight

Calculates total weight of all authorization keys

pub fn total_keys_weight_excluding(&self, account_hash: AccountHash) -> Weight

Calculates total weight of all authorization keys excluding a given key

Trait Implementations

impl Clone for AssociatedKeys

fn clone(&self) -> AssociatedKeys

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AssociatedKeys

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

Formats the value using the given formatter.

impl Default for AssociatedKeys

fn default() -> AssociatedKeys

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AssociatedKeys

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<AssociatedKeys> for BTreeMap<AccountHash, Weight>

fn from(associated_keys: AssociatedKeys) -> Self

Converts to this type from the input type.

impl From<BTreeMap<AccountHash, Weight>> for AssociatedKeys

fn from(associated_keys: BTreeMap<AccountHash, Weight>) -> Self

Converts to this type from the input type.

impl FromBytes for AssociatedKeys

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 Ord for AssociatedKeys

fn cmp(&self, other: &AssociatedKeys) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for AssociatedKeys

fn eq(&self, other: &AssociatedKeys) -> 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 PartialOrd for AssociatedKeys

fn partial_cmp(&self, other: &AssociatedKeys) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for AssociatedKeys

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 AssociatedKeys

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>.
