Struct sp_inherents::InherentDataProviders

pub struct InherentDataProviders { /* fields omitted */ }

All InherentData providers.

Implementations

impl InherentDataProviders

pub fn new() -> Self

Create a new instance.

pub fn register_provider<P: ProvideInherentData + Send + Sync + 'static>(
    &self,
    provider: P
) -> Result<(), Error>

Register an InherentData provider.

The registration order is preserved and this order will also be used when creating the inherent data.

Result

Will return an error, if a provider with the same identifier already exists.

pub fn has_provider(&self, identifier: &InherentIdentifier) -> bool

Returns if a provider for the given identifier exists.

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

Create inherent data.

pub fn error_to_string(
    &self,
    identifier: &InherentIdentifier,
    error: &[u8]
) -> String

Converts a given encoded error into a String.

Useful if the implementation encounters an error for an identifier it does not know.
