Enum Error 

pub enum Error {
    HmacSha256 {
        source: InvalidLength,
    },
    KeyGripEmpty,
    Argon2Hash {
        source: Error,
    },
    Argon2Parse {
        source: Error,
    },
}

Variants

HmacSha256

封装 hmac crate 的 InvalidLength，使调用方可直接使用 .context(HmacSha256Snafu)。

Fields

source: InvalidLength

KeyGripEmpty

密钥列表为空，无法执行签名或验签操作。

Argon2Hash

Argon2 哈希计算失败（参数异常，正常不会发生）。

Fields

source: Error

Argon2Parse

解析已存储的 Argon2 PHC 串失败（库中哈希损坏 / 校验阶段内部异常）。

Fields

source: Error

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

where Self: Debug + Display,

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl ErrorCompat for Error

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<Error> for Error

fn from(val: Error) -> Self

Converts to this type from the input type.
