Implementations§

source§

impl SigValue

source

pub fn weight(&self) -> Weight

Get weight for signature verification. Considers the type of signature. 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.
