Struct Set 

pub struct Set {
    pub now: Now,
}

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 [Config::MinimumPeriod].

The dispatch origin for this call must be None.

This dispatch class is Mandatory to ensure it gets executed in the block. Be aware that changing the complexity of this call could result exhausting the resources in a block to execute any other calls.

Complexity

• O(1) (Note that implementations of OnTimestampSet must also be O(1))
• 1 storage read and 1 storage mutation (codec O(1) because of DidUpdate::take in on_finalize)
• 1 event handler on_timestamp_set. Must be O(1).

Trait Implementations

impl Debug for Set

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

Formats the value using the given formatter.

impl DecodeAsExtrinsic for Set

fn is_extrinsic(pallet_name: &str, call_name: &str) -> bool

Returns true if the given pallet and call names match this extrinsic.

impl DecodeAsFields for Set

fn decode_as_fields<'info, R: TypeResolver>( input: &mut &[u8], fields: &mut dyn FieldIter<'info, R::TypeId>, types: &'info R, ) -> Result<Self, Error>

Given some bytes and some fields denoting their structure, attempt to decode.

impl EncodeAsFields for Set

fn encode_as_fields_to<ScaleEncodeResolver: TypeResolver>( &self, __encode_as_type_fields: &mut dyn FieldIter<'_, ScaleEncodeResolver::TypeId>, __encode_as_type_types: &ScaleEncodeResolver, __encode_as_type_out: &mut Vec<u8>, ) -> Result<(), Error>

Given some fields describing the shape of a type, attempt to encode to that shape.

fn encode_as_fields<R>( &self, fields: &mut dyn FieldIter<'_, <R as TypeResolver>::TypeId, Item = Field<'_, <R as TypeResolver>::TypeId>>, types: &R, ) -> Result<Vec<u8>, Error>

where R: TypeResolver,

This is a helper function which internally calls EncodeAsFields::encode_as_fields_to. Prefer to implement that instead.

impl EncodeAsType for Set

fn encode_as_type_to<ScaleEncodeResolver: TypeResolver>( &self, __encode_as_type_type_id: ScaleEncodeResolver::TypeId, __encode_as_type_types: &ScaleEncodeResolver, __encode_as_type_out: &mut Vec<u8>, ) -> Result<(), Error>

Given some type_id, types, a context and some output target for the SCALE encoded bytes, attempt to SCALE encode the current value into the type given by type_id.

fn encode_as_type<R>( &self, type_id: <R as TypeResolver>::TypeId, types: &R, ) -> Result<Vec<u8>, Error>

where R: TypeResolver,

This is a helper function which internally calls EncodeAsType::encode_as_type_to. Prefer to implement that instead.

impl IntoVisitor for Set

type AnyVisitor<ScaleDecodeTypeResolver: TypeResolver> = Visitor<ScaleDecodeTypeResolver>

The visitor type used to decode SCALE encoded bytes to Self.

fn into_visitor<ScaleDecodeTypeResolver: TypeResolver>() -> Self::AnyVisitor<ScaleDecodeTypeResolver>

A means of obtaining this visitor.
