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) -> Selfwhere 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 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<T> AddContext<T, AnyError, AnyError> for Result<T, AnyError>

When adding context info, convert an AnyError to another AnyError.

fn add_context<D, F>(self, f: F) -> Result<T, AnyError>where D: Display, F: FnOnce() -> D,

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 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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl<E> From<&E> for AnyErrorwhere E: Error + 'static,

fn from(e: &E) -> Self

Converts to this type from the input type.

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: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
