Struct ssi_claims::VerificationParameters

pub struct VerificationParameters<R, L1 = ContextLoader, L2 = ()> {
    pub resolver: R,
    pub json_ld_loader: L1,
    pub eip712_types_loader: L2,
    pub date_time: Option<DateTime<Utc>>,
}

Common verification parameters.

The VerifiableClaims::verify function expects a set of verification parameters necessary for the validation of claims and signature.

Required parameters depend on the actual type of claims and signature you want to validate, however we can identify a subset of parameters that are commonly required, namely:

• A public key resolver,
• a JSON-LD document loader,
• an EIP-712 types definition loader,
• the date and time.

This type provides this subset of parameters. In most cases, this will be sufficient to verify all your secured claims.

Fields

resolver: R

Public key resolver.

json_ld_loader: L1

JSON-LD loader.

eip712_types_loader: L2

EIP-712 types loader.

date_time: Option<DateTime<Utc>>

Date-time.

If None, the current date time is used.
