Implementations§

Source §

impl Error

Source

pub fn panic(self) -> !

Source

pub fn from_panic(e: Box<dyn Any + Send + 'static>) -> Self

Source

pub fn into_panic(self) -> Box<dyn Any + Send>

Source

pub fn panic_str(self) -> Option<&'static str>

Get the panic message string.

Source

pub fn is_panic(&self) -> bool

Check if the Error is trafficking a panic object.

Source §

impl Error

Source

pub fn from_errno() -> Self

Source

pub fn bad_database(message: &'static str) -> Self

Source

pub fn sanitized_message(&self) -> String

Sanitizes public-facing errors that can leak sensitive information.

Source

pub fn message(&self) -> String

Generate the error message string.

Source

pub fn kind(&self) -> ErrorKind

Returns the Matrix error code / error kind

Source

pub fn status_code(&self) -> StatusCode

Returns the HTTP error code or closest approximation based on error variant.

Source

pub fn is_not_found(&self) -> bool

Returns true for “not found” errors. This means anything that qualifies as a “not found” from any variant’s contained error type. This call is often used as a special case to eliminate a contained Option with a Result where Ok(None) is instead Err(e) if e.is_not_found().

1.0.0 · Source§

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
