Struct AccountSignatures 

#[repr(transparent)]
pub struct AccountSignatures {
    pub sigs: BTreeMap<u8, CredentialSignatures>,
}

Account signatures are constructed similarly to transaction signatures. The only difference is that account signatures use as account nonce the value 0 when signing. This is to ensure that the user does not accidentally sign a valid transaction. As such account signatures can be used to sign messages in wallets that can then be verified in a smart contract or by a backend.

Account signatures should be thought of as a nested map, indexed on the outer layer by credential indices, and the inner map maps key indices to Signatures.

Fields

sigs: BTreeMap<u8, CredentialSignatures>

Implementations

impl AccountSignatures

pub fn singleton(signature: Signature) -> Self

Create the account signature type from a single signature at credential and key indices 0. This is a helper function to create the type when dealing with a single-signer account (in contrast to a multi-sig account). The naming singleton is used in Concordium’s code base to indicate that there is only one element in the maps.

Trait Implementations

impl Debug for AccountSignatures

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AccountSignatures

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AccountSignatures

fn eq(&self, other: &AccountSignatures) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AccountSignatures

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
