Struct webauthn_authenticator_rs::ctap2::commands::CredentialStorageMetadata

pub struct CredentialStorageMetadata {
    pub existing_resident_credentials_count: u32,
    pub max_possible_remaining_resident_credentials_count: u32,
}

Available on crate features ctap2-management and ctap2 only.

Discoverable credential storage metadata, returned by CredentialManagementAuthenticator::get_credentials_metadata().

Fields

existing_resident_credentials_count: u32

Number of discoverable credentials present on the authenticator.

max_possible_remaining_resident_credentials_count: u32

Estimated number of additional discoverable credentials which could be created on this authenticator, assuming minimally-sized fields for all requests (ie: errs high).

This value may vary over time, depending on the size of individual discoverable credentials, and the token’s storage allocation strategy.

CTAP compatibility

On authenticators supporting CTAP 2.1 or later, a pessimistic estimate (ie: presuming maximally-sized credentials) might be available without authentication in GetInfoResponse::remaining_discoverable_credentials.

Trait Implementations

impl Debug for CredentialStorageMetadata

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

Formats the value using the given formatter.

impl Default for CredentialStorageMetadata

fn default() -> CredentialStorageMetadata

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CredentialStorageMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CredentialStorageMetadata

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<&mut BTreeMap<u32, Value>> for CredentialStorageMetadata

type Error = WebauthnCError

The type returned in the event of a conversion error.

fn try_from(raw: &mut BTreeMap<u32, Value>) -> Result<Self, Self::Error>

Performs the conversion.
