Enum MacaroonError 

pub enum MacaroonError {
    InitializationError,
    CryptoError(&'static str),
    IncompleteMacaroon(&'static str),
    IncompleteCaveat(&'static str),
    DeserializationError(String),
    CaveatNotSatisfied(String),
    DischargeNotUsed,
    InvalidSignature,
}

Represents all of the errors that can arise when creating, deserializing, or verifying macaroons.

Variants

InitializationError

Only raised by the initialize() function, when there is a problem initializing the lower-level crypto library

CryptoError(&'static str)

Represents a runtime error in the lower-level cryptographic library, or situations like zero-length ciphertext.

IncompleteMacaroon(&'static str)

Can occur when constructing or deserializing a Macaroon and expected fields are not present.

IncompleteCaveat(&'static str)

Can occur when constructing or deserializing Caveat and expected fields are not present.

DeserializationError(String)

Represents a broad category of issues when parsing a macaroon token in any format.

CaveatNotSatisfied(String)

Arises when verifying a Macaroon, when it has any caveat not satisfied by any “exact” or “general” satisfiers configured on the Verifier. Indicates a failure to authenticate the macaroon.

DischargeNotUsed

Arises when verifying a Macaroon, with a set of discharges configured on the verifier, and one or more are not used during the verification process. Indicates a failure to authenticate the macaroon.

InvalidSignature

Arises when verifying a Macaroon, and the signature does not match what is expected. Indicates a failure to authenticate the macaroon.

Trait Implementations

impl Debug for MacaroonError

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

Formats the value using the given formatter.

impl Display for MacaroonError

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

Formats the value using the given formatter.

impl Error for MacaroonError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
