Implementations

impl Error

pub fn http_status(status: u16, message: impl Into<String>) -> Self

Create an HTTP status error.

pub fn missing(field: impl Into<String>) -> Self

Create a missing field error.

pub fn io(message: impl Into<String>) -> Self

Create an IO error with custom message.

pub fn http_protocol(message: impl Into<String>) -> Self

Create an HTTP protocol error.

pub fn connection(message: impl Into<String>) -> Self

Create a connection error.

pub fn timeout(message: impl Into<String>) -> Self

Create a timeout error.

pub fn tls(message: impl Into<String>) -> Self

Create a TLS error.

pub fn quic(message: impl Into<String>) -> Self

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, __formatter: &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(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(err: ParseError) -> Self

Converts to this type from the input type.
