Struct sp_timestamp::InherentDataProvider

pub struct InherentDataProvider { /* private fields */ }

Provide duration since unix epoch in millisecond for timestamp inherent.

Implementations

impl InherentDataProvider

pub fn from_system_time() -> Self

Create Self while using the system time to get the timestamp.

pub fn new(timestamp: InherentType) -> Self

Create Self using the given timestamp.

pub fn with_max_drift(self, max_drift: Duration) -> Self

With the given maximum drift.

By default the maximum drift is 60 seconds.

The maximum drift is used when checking the inherents of a runtime. If the current timestamp plus the maximum drift is smaller than the timestamp in the block, the block will be rejected as being too far in the future.

pub fn timestamp(&self) -> InherentType

Returns the timestamp of this inherent data provider.

Trait Implementations

impl Deref for InherentDataProvider

type Target = InherentType

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl InherentDataProvider for InherentDataProvider

fn provide_inherent_data(
    &self,
    inherent_data: &mut InherentData
) -> Result<(), Error>

Provide inherent data that should be included in a block.

fn try_handle_error<'life0, 'life1, 'life2, 'async_trait>(
    &'life0 self,
    identifier: &'life1 InherentIdentifier,
    error: &'life2 [u8]
) -> Pin<Box<dyn Future<Output = Option<Result<(), Error>>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    'life2: 'async_trait,
    Self: 'async_trait, 

Convert the given encoded error to a string.

fn create_inherent_data(&self) -> Result<InherentData, Error>

Convenience function for creating InherentData.
