Struct anyerror::AnyError

pub struct AnyError { /* private fields */ }

AnyError is a serializable wrapper Error.

It is can be used to convert other Error into a serializable Error for transmission, with most necessary info kept.

let e = AnyError::new(&fmt::Error{}).add_context(|| "example");
assert_eq!("core::fmt::Error: an error occurred when formatting an argument while: example", e.to_string());

Implementations

impl AnyError

pub fn error(msg: impl ToString) -> Self

Create an ad-hoc error with a string message

pub fn new<E>(e: &E) -> Self where
    E: Error + 'static, 

Convert some Error to AnyError.

• If there is a source() in the input error, it is also converted to AnyError, recursively.
• A new backtrace will be built if there is not.

pub fn from_dyn(e: &(dyn Error + 'static), typ: Option<String>) -> Self

pub fn with_backtrace(self) -> Self

pub fn add_context<D: Display, F: FnOnce() -> D>(self, ctx: F) -> Self

pub fn get_type(&self) -> Option<&str>

pub fn backtrace(&self) -> Option<&str>

Trait Implementations

impl Clone for AnyError

fn clone(&self) -> AnyError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AnyError

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

Formats the value using the given formatter.

impl Default for AnyError

fn default() -> AnyError

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AnyError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for AnyError

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

Formats the value using the given formatter.

impl Error for AnyError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

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

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl PartialEq<AnyError> for AnyError

fn eq(&self, other: &AnyError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &AnyError) -> bool

This method tests for !=.

impl Serialize for AnyError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
