Struct DeliveryFailure 

pub struct DeliveryFailure {
    pub kind: DeliveryFailureKind,
    pub attrs: Flattrs,
}

A structured delivery failure with optional metadata.

Fields

kind: DeliveryFailureKind

The delivery failure kind.

attrs: Flattrs

Additional keyed metadata for higher-level delivery features.

Implementations

impl DeliveryFailure

pub fn new(kind: impl Into<DeliveryFailureKind>) -> Self

Create a delivery failure with no additional metadata.

pub fn with_attrs(kind: impl Into<DeliveryFailureKind>, attrs: Flattrs) -> Self

Create a delivery failure with additional keyed metadata.

pub fn render_bounded(&self) -> String

Render this failure for human-facing diagnostics.

Trait Implementations

impl Clone for DeliveryFailure

fn clone(&self) -> DeliveryFailure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeliveryFailure

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DeliveryFailure

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DeliveryFailure

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

Formats the value using the given formatter.

impl Error for DeliveryFailure

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 Named for DeliveryFailure

fn typename() -> &'static str

The globally unique type name for the type. This should typically be the fully qualified Rust name of the type.

fn typehash() -> u64

A globally unique hash for this type. TODO: actually enforce perfect hashing

fn typeid() -> TypeId

The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.

fn port() -> u64

A globally unique numeric identifier for this type.

fn arm(&self) -> Option<&'static str>

If the named type is an enum, this returns the name of the arm of the value self.

unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>

An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.

impl Serialize for DeliveryFailure

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
