Struct frame_support::pallet_prelude::InherentData
source · pub struct InherentData { /* private fields */ }
Expand description
Inherent data to include in a block.
Implementations
sourceimpl InherentData
impl InherentData
sourcepub fn new() -> InherentData
pub fn new() -> InherentData
Create a new instance.
sourcepub fn put_data<I>(
&mut self,
identifier: [u8; 8],
inherent: &I
) -> Result<(), Error>where
I: Encode,
pub fn put_data<I>(
&mut self,
identifier: [u8; 8],
inherent: &I
) -> Result<(), Error>where
I: Encode,
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!
sourcepub fn replace_data<I>(&mut self, identifier: [u8; 8], inherent: &I)where
I: Encode,
pub fn replace_data<I>(&mut self, identifier: [u8; 8], inherent: &I)where
I: Encode,
Replace the data for an inherent.
If it does not exist, the data is just inserted.
sourcepub fn get_data<I>(&self, identifier: &[u8; 8]) -> Result<Option<I>, Error>where
I: Decode,
pub fn get_data<I>(&self, identifier: &[u8; 8]) -> Result<Option<I>, Error>where
I: Decode,
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.
