Struct Error 

pub struct Error { /* private fields */ }

Error type returned across all Sift crates.

Implementations

impl Error

pub fn new<E>(kind: ErrorKind, err: E) -> Self

where E: StdError + Send + Sync + 'static,

Initializes an Error.

pub fn new_msg<S: AsRef<str>>(kind: ErrorKind, msg: S) -> Self

Initializes an Error with a generic message.

pub fn new_general<S: AsRef<str>>(msg: S) -> Self

Initializes a general catch-all type of Error. Contributors should be careful not to use this unless strictly necessary.

pub fn new_arg_error<S: AsRef<str>>(msg: S) -> Self

Used for user-errors that have to do with bad arguments.

pub fn new_empty_response<S: AsRef<str>>(msg: S) -> Self

Tonic response types usually return optional types that we need to handle; if responses are empty then this is the appropriate way to initialize an Error for that situation, though this has never been observed.

pub fn kind(&self) -> ErrorKind

Get the underlying error kind.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.
