source · [−]

pub struct InherentData { /* private fields */ }

Expand description

Inherent data to include in a block.

Implementations

source

impl InherentData

source

pub fn new() -> InherentData

Create a new instance.

source

pub fn put_data(
 &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!

source

pub fn replace_data(&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.

source

pub fn get_data(&self, identifier: &[u8 ; 8]) -> Result<Option, 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.

source

pub fn len(&self) -> usize

Get the number of inherents in this instance
