Struct sp_inherents::InherentDataProviders
source · [−]pub struct InherentDataProviders { /* private fields */ }Expand description
All InherentData providers.
Implementations
sourceimpl InherentDataProviders
impl InherentDataProviders
sourcepub fn register_provider<P: ProvideInherentData + Send + Sync + 'static>(
&self,
provider: P
) -> Result<(), Error>
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.
sourcepub fn has_provider(&self, identifier: &InherentIdentifier) -> bool
pub fn has_provider(&self, identifier: &InherentIdentifier) -> bool
Returns if a provider for the given identifier exists.
sourcepub fn create_inherent_data(&self) -> Result<InherentData, Error>
pub fn create_inherent_data(&self) -> Result<InherentData, Error>
Create inherent data.
sourcepub fn error_to_string(
&self,
identifier: &InherentIdentifier,
error: &[u8]
) -> String
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.
