[−][src]Struct frame_system::offchain::Signer
Provides an implementation for signing transaction payloads.
Keys used for signing are defined when instantiating the signer object. Signing can be done using:
- All supported keys in the keystore
- Any of the supported keys in the keystore
- An intersection of in-keystore keys and the list of provided keys
The signer is then able to:
- Submit a unsigned transaction with a signed payload
- Submit a signed transaction
Implementations
impl<T: SigningTypes, C: AppCrypto<T::Public, T::Signature>, X> Signer<T, C, X>[src]
pub fn all_accounts() -> Signer<T, C, ForAll>[src]
Use all available keys for signing.
pub fn any_account() -> Signer<T, C, ForAny>[src]
Use any of the available keys for signing.
pub fn with_filter(self, accounts: Vec<T::Public>) -> Self[src]
Use provided accounts for signing.
Note that not all keys will be necessarily used. The provided vector of accounts will be intersected with the supported keys in the keystore and the resulting list will be used for signing.
pub fn can_sign(&self) -> bool[src]
Check if there are any keys that could be used for signing.
