Struct Error 

#[repr(C)]
pub struct Error {
    pub code: Code,
    pub subject: Subject,
    pub state: State,
    pub location: Location,
}

mfio’s error type.

This type consists of 4 distinct pieces:

• code, representing equivalent HTTP status code, which may not be descriptive, and often falls back to INTERNAL_ERROR, representing HTTP code 500.
• subject, represents what errored out.
• state, represents what kind of error state was reached.
• location, where in the program the error occured.

Fields

code: Code

subject: Subject

state: State

location: Location

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

Available on crate feature std only.

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 ErrorSpecify for Error

fn code(self, code: Code) -> Self

fn subject(self, subject: Subject) -> Self

fn state(self, state: State) -> Self

fn location(self, location: Location) -> Self

impl From<Error> for Error

Available on crate feature std only.

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for StatusCode

Available on crate feature http only.

fn from(_: Error) -> Self

Converts to this type from the input type.

impl From<ErrorKind> for Error

Available on crate feature std only.

fn from(kind: ErrorKind) -> Self

Converts to this type from the input type.

impl From<Infallible> for Error

fn from(_: Infallible) -> Self

Converts to this type from the input type.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntError for Error

fn into_int_err(self) -> NonZeroI32

fn from_int_err(err: NonZeroI32) -> Self

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

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

impl StructuralPartialEq for Error

impl TryFrom<StatusCode> for Error

Available on crate feature http only.

type Error = ()

The type returned in the event of a conversion error.

fn try_from(code: StatusCode) -> Result<Self, Self::Error>

Performs the conversion.
