Session

avail_rust_client::transaction_api

Struct Session 

Source 
pub struct Session(/* private fields */);
Expand description

Builds extrinsics for the session pallet.

The helper clones the underlying client; composing calls does not contact the node until the resulting SubmittableTransaction is signed or submitted.

Implementations§

Source§

impl Session

Source

pub fn set_key( &self, babe: impl Into<HashString>, grandpa: impl Into<HashString>, authority_discovery: impl Into<HashString>, im_online: impl Into<HashString>, proof: Vec<u8>, ) -> SubmittableTransaction

Updates the node’s session keys with new authorities and proof data.

§Panics

Panics when any supplied key fails to decode into an H256 hash.

§Arguments
  • babe - BABE authority key encoded as a hash string.
  • grandpa - GRANDPA authority key encoded as a hash string.
  • authority_discovery - Authority discovery key encoded as a hash string.
  • im_online - Im-online session key encoded as a hash string.
  • proof - Proof bytes returned by the session key generator.
§Returns

Returns a SubmittableTransaction that sets the supplied session keys.

§Errors

Does not perform network calls; transaction construction never fails.

Source

pub fn purge_key(&self) -> SubmittableTransaction

Removes the stored session keys from on-chain storage.

§Returns

Returns a SubmittableTransaction that clears session keys for the signing account.

§Errors

Does not perform network calls; transaction construction never fails.
