Struct NeuErrImpl 

pub struct NeuErrImpl { /* private fields */ }

Inner implementation of NeuErr that implements Error.

Implementations

impl NeuErrImpl

pub const fn wrap(self) -> NeuErr

Wrap this error back into a NeuErr that offers all of the functionality.

pub fn context<C>(self, context: C) -> Self

where C: Into<Cow<'static, str>>,

Add human context to the error.

pub fn attach<C>(self, context: C) -> Self

where C: AnyDebugSendSync + 'static,

Add machine context to the error.

This will not override existing attachments. If you want to replace and override any existing attachments of the same type, use attach_override instead.

pub fn attach_override<C>(self, context: C) -> Self

where C: AnyDebugSendSync + 'static,

Set machine context in the error.

This will override existing attachments of the same type. If you want to add attachments of the same type, use attach instead.

pub fn attachments<C>(&self) -> impl Iterator<Item = &C>

where C: AnyDebugSendSync + 'static,

Get an iterator over the machine context attachments of the given type.

pub fn attachment<C>(&self) -> Option<&C>

where C: AnyDebugSendSync + 'static,

Get the machine context attachment of the given type.

Trait Implementations

impl Debug for NeuErrImpl

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

Formats the value using the given formatter.

impl Default for NeuErrImpl

fn default() -> NeuErrImpl

Returns the “default value” for a type.

impl Display for NeuErrImpl

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

Formats the value using the given formatter.

impl Error for NeuErrImpl

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<NeuErr> for NeuErrImpl

fn from(err: NeuErr) -> Self

Converts to this type from the input type.

impl Termination for NeuErrImpl

Available on crate feature std only.

fn report(self) -> ExitCode

Is called to get the representation of the value as status code. This status code is returned to the operating system.
