Enum pallet_timestamp::Call

pub enum Call<T: Trait> {
    set(T::Moment),
    // some variants omitted
}

Dispatchable calls.

Each variant of this enum maps to a dispatchable function from the associated module.

Variants

set(T::Moment)

Set the current time.

This call should be invoked exactly once per block. It will panic at the finalization phase, if this call hasn't been invoked by that time.

The timestamp should be greater than the previous one by the amount specified by MinimumPeriod.

The dispatch origin for this call must be Inherent.

Trait Implementations

impl<T: Trait> Clone for Call<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Trait> Debug for Call<T>

fn fmt(&self, _f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl<T: Trait> Decode for Call<T> where
    T::Moment: HasCompact, 

fn decode<DecIn: Input>(input: &mut DecIn) -> Result<Self, Error>

Attempt to deserialise the value from input.

impl<T: Trait> Dispatchable for Call<T>

type Trait = T

...

type Origin = T::Origin

Every function call from your runtime has an origin, which specifies where the extrinsic was generated from. In the case of a signed extrinsic (transaction), the origin contains an identifier for the caller. The origin can be empty in the case of an inherent extrinsic.

type Info = DispatchInfo

An opaque set of information attached to the transaction. This could be constructed anywhere down the line in a runtime. The current Substrate runtime uses a struct with the same name to represent the dispatch class and weight.

type PostInfo = PostDispatchInfo

Additional information that is returned by dispatch. Can be used to supply the caller with information about a Dispatchable that is ownly known post dispatch.

fn dispatch(self, _origin: Self::Origin) -> DispatchResultWithPostInfo

Actually dispatch this call and return the result of it.

impl<T: Trait> Encode for Call<T> where
    T::Moment: HasCompact, 

fn encode_to<EncOut: Output>(&self, dest: &mut EncOut)

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

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

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

impl<T: Trait> EncodeLike<Call<T>> for Call<T> where
    T::Moment: HasCompact, 

impl<T: Trait> Eq for Call<T>

impl<T: Trait> 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]

Return all function names.

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

fn get_dispatch_info(&self) -> DispatchInfo

Return a DispatchInfo, containing relevant information of this dispatch.

impl<T: Trait> 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 ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
