Struct frame_support::inherent::InherentData [−][src]
pub struct InherentData { /* fields omitted */ }
Expand description
Inherent data to include in a block.
Implementations
Create a new instance.
Put data for an inherent into the internal storage.
Return
Returns Ok(())
if the data could be inserted and no data for an inherent with the same
identifier existed, otherwise an error is returned.
Inherent identifiers need to be unique, otherwise decoding of these values will not work!
Replace the data for an inherent.
If it does not exist, the data is just inserted.
Returns the data for the requested inherent.
Return
Ok(Some(I))
if the data could be found and deserialized.Ok(None)
if the data could not be found.Err(_)
if the data could be found, but deserialization did not work.
