Struct LazyError

pub struct LazyError<'a, E> {
    pub field_name: Option<Cow<'a, str>>,
    pub error: E,
    /* private fields */
}

An error for lazily written multipart requests, including the original error as well as the field which caused the error, if applicable.

Fields

field_name: Option<Cow<'a, str>>

The field that caused the error. If None, there was a problem opening the stream to write or finalizing the stream.

error: E

The inner error.

Trait Implementations

impl<'a, E: Debug> Debug for LazyError<'a, E>

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

Formats the value using the given formatter.

impl<'a, E: Display> Display for LazyError<'a, E>

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

Formats the value using the given formatter.

impl<'a, E: Error> Error for LazyError<'a, E>

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

Returns the lower-level source of this error, if any.

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<'a> Into<Error> for LazyError<'a, Error>

Take self.error, discarding self.field_name.

fn into(self) -> Error

Converts this type into the (usually inferred) input type.
