Struct ContextError

pub struct ContextError<E, C> {
    pub error: E,
    pub context: C,
}

A wrapper error type that attaches contextual information to an error

Fields

error: E

The original error

context: C

The context attached to the error

Implementations

impl<E, C> ContextError<E, C>

pub fn new(error: E, context: C) -> Self

Create a new context error wrapping the original error

pub fn into_error(self) -> E

Extract the original error, discarding the context

pub fn map_context<D, F>(self, f: F) -> ContextError<E, D>

where F: FnOnce(C) -> D,

Map the context to a new type using the provided function

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

where D: Display + Debug + Send + Sync + 'static,

Add another layer of context to this error

Trait Implementations

impl<E: Debug, C: Debug> Debug for ContextError<E, C>

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

Formats the value using the given formatter.

impl<E: Display, C: Display> Display for ContextError<E, C>

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

Formats the value using the given formatter.

impl<E: Error + 'static, C: Display + Debug + Send + Sync + 'static> Error for ContextError<E, C>

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.

fn caption(&self) -> &'static str

Returns a human-readable caption for the error

fn is_retryable(&self) -> bool

Returns true if the operation can be retried

fn is_fatal(&self) -> bool
