Interface AsyncBuilder<T>

Example

class SignedDataBuilder implements AsyncBuilder<SignedData> {
    private data: Uint8Array
    private signers: Signer[] = []

    setData(data: Uint8Array): this {
        this.data = data
        return this
    }

    addSigner(signer: Signer): this {
        this.signers.push(signer)
        return this
    }

    async build(): Promise<SignedData> {
        // Perform async cryptographic operations
        const signatures = await this.computeSignatures()
        return new SignedData(this.data, signatures)
    }
}

const signedData = await new SignedDataBuilder()
    .setData(documentBytes)
    .addSigner(signer)
    .build()
