Struct CtxErrorImpl 

pub struct CtxErrorImpl { /* private fields */ }

Inner implementation of CtxError that implements Error.

Implementations

impl CtxErrorImpl

pub const fn wrap(self) -> CtxError

Wrap this error back into a CtxError 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 CtxErrorImpl

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

Formats the value using the given formatter.

impl Default for CtxErrorImpl

fn default() -> CtxErrorImpl

Returns the “default value” for a type.

impl Display for CtxErrorImpl

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

Formats the value using the given formatter.

impl Error for CtxErrorImpl

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<CtxError> for CtxErrorImpl

fn from(err: CtxError) -> Self

Converts to this type from the input type.

impl Termination for CtxErrorImpl

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.
