Implementations

impl AssociatedKeys

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

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

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

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

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 Eq for AssociatedKeys

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.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<AssociatedKeys> 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: &AssociatedKeys) -> bool

This method tests for !=.

impl PartialOrd<AssociatedKeys> 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: &AssociatedKeys) -> bool

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

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

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

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

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

fn ge(&self, other: &AssociatedKeys) -> 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 StructuralEq for AssociatedKeys

impl StructuralPartialEq for AssociatedKeys

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 into_bytes(self) -> Result<Vec<u8>, Error>

Consumes self and serializes to a Vec<u8>.
