Required Methods§

source

fn for_sig_type<R>( &self, for_sr25519: impl FnOnce() -> R, for_ed25519: impl FnOnce() -> R, for_secp256k1: impl FnOnce() -> R ) -> Option<R>

Provided Methods§

source

fn weight_for_sig_type<T>( &self, for_sr25519: impl FnOnce() -> Weight, for_ed25519: impl FnOnce() -> Weight, for_secp256k1: impl FnOnce() -> Weight ) -> Weightwhere T: Config,

source

fn count_sig_types( auths: impl IntoIterator<Item = impl Borrow<Self>> ) -> SigTypes<u64>

Return counts of different signature types in given SignatureWithNonce as 3-Tuple as (no. of Sr22519 sigs, no. of Ed25519 Sigs, no. of Secp256k1 sigs). Useful for weight calculation and thus the return type is in Weight but realistically, it should fit in a u8

source

fn auth_weight( auths: impl IntoIterator<Item = impl Borrow<Self>>, db_weights: RuntimeDbWeight ) -> Weight

Computes weight of the given SignatureWithNonce. Considers the no. and types of signatures and no. of reads. Disregards message size as messages are hashed giving the same output size and hashing itself is very cheap. The extrinsic using it might decide to consider adding some weight proportional to the message size.
