Trait sp_inherents::CreateInherentDataProviders

pub trait CreateInherentDataProviders<Block: BlockT, ExtraArgs>: Send + Sync {
    type InherentDataProviders: InherentDataProvider;
    fn create_inherent_data_providers<'life0, 'async_trait>(
        &'life0 self, 
        parent: Block::Hash, 
        extra_args: ExtraArgs
    ) -> Pin<Box<dyn Future<Output = Result<Self::InherentDataProviders, Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>
    where
        'life0: 'async_trait,
        Self: 'async_trait;
}

Something that can create inherent data providers.

It is possible for the caller to provide custom arguments to the callee by setting the ExtraArgs generic parameter.

The crate already provides some convience implementations of this trait for Box<dyn CreateInherentDataProviders> and closures. So, it should not be required to implement this trait manually.

Associated Types

type InherentDataProviders: InherentDataProvider

The inherent data providers that will be created.

Required methods

fn create_inherent_data_providers<'life0, 'async_trait>(
    &'life0 self,
    parent: Block::Hash,
    extra_args: ExtraArgs
) -> Pin<Box<dyn Future<Output = Result<Self::InherentDataProviders, Box<dyn Error + Send + Sync>>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Create the inherent data providers at the given parent block using the given extra_args.
