Implementations

impl ProviderMetadata

pub fn validate( self, issuer: &str, ) -> Result<VerifiedProviderMetadata, ProviderMetadataVerificationError>

Validate this ProviderMetadata according to the OpenID Connect Discovery Spec 1.0.

Parameters

• issuer: The issuer that was discovered to get this ProviderMetadata.

Errors

Will return Err if validation fails.

pub fn insecure_verify_metadata( self, ) -> Result<VerifiedProviderMetadata, ProviderMetadataVerificationError>

Verify this ProviderMetadata.

Contrary to ProviderMetadata::validate(), it only checks that the required fields are present.

This can be used during development to test against a local OpenID Provider, for example.

Parameters

• issuer: The issuer that was discovered to get this ProviderMetadata.

Errors

Will return Err if a required field is missing.

Warning

It is not recommended to use this method in production as it doesn’t ensure that the issuer implements the proper security practices.
