Contains one variant per dispatchable that can be called by an extrinsic.

Variants

set_keys

Fields

keys: T::Keys

proof: Vec<u8>

Sets the session key(s) of the function caller to keys. Allows an account to set its session key prior to becoming a validator. This doesn’t take effect until the next session.

The dispatch origin of this function must be signed.

• Complexity: O(1). Actual cost depends on the number of length of T::Keys::key_ids() which is fixed.
• DbReads: origin account, T::ValidatorIdOf, NextKeys
• DbWrites: origin account, NextKeys
• DbReads per key id: KeyOwner
• DbWrites per key id: KeyOwner

purge_keys

Fields

Removes any session key(s) of the function caller.

This doesn’t take effect until the next session.

The dispatch origin of this function must be Signed and the account must be either be convertible to a validator ID using the chain’s typical addressing system (this usually means being a controller account) or directly convertible into a validator ID (which usually means being a stash account).

• Complexity: O(1) in number of key types. Actual cost depends on the number of length of T::Keys::key_ids() which is fixed.
• DbReads: T::ValidatorIdOf, NextKeys, origin account
• DbWrites: NextKeys, origin account
• DbWrites per key id: KeyOwner

) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn skip<I>(input: &mut I) -> Result<(), Error>where
    I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<T: Config> Encode for Call<T>

fn encode_to<__CodecOutputEdqy: Output + ?Sized>(

fn using_encoded<R, F>(&self, f: F) -> Rwhere
    F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T: Config> GetCallName for Call<T>

fn get_call_name(&self) -> &'static str

Return the function name of the Call.

fn get_call_names() -> &'static [&'static str]

impl<T: Config> GetDispatchInfo for Call<T>

fn get_dispatch_info(&self) -> DispatchInfo

👎Deprecated: Trait has moved to frame_support::dispatch

impl<T: Config> PartialEq<Call<T>> for Call<T>

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

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

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

fn dispatch_bypass_filter(
    self,
    origin: Self::RuntimeOrigin
) -> DispatchResultWithPostInfo
