Implementations

impl Error

pub fn invalid_json(position: usize, message: impl Into<String>) -> Self

Create an invalid JSON error

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

Create an invalid frame error

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

Create a buffer error

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

Create a memory error

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

Create a generic error

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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(err: Error) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for Error

fn from(err: Utf8Error) -> Self

Converts to this type from the input type.
