Function pre_signature

pub async fn pre_signature<R: Relay, S: PreSignSetupMessage>(
    setup: S,
    seed: Seed,
    relay: R,
) -> Result<PreSign, SignError>

Executes the pre-signature phase of the DSG protocol

This function runs only the pre-signature phase of the protocol, producing a pre-signature that can be used later to sign messages.

Type Parameters

• R: Type implementing the Relay trait for message communication
• S: Type implementing the PreSignSetupMessage trait for setup parameters

Arguments

• setup: Setup parameters for the protocol
• seed: Random seed for generating random values
• relay: Message relay for communication between parties

Returns

A Result containing either:

• Ok(PreSign): The pre-signature result
• Err(SignError): An error if the protocol fails
