Struct Error 

pub struct Error {
    pub action: String,
    pub message: String,
    pub domain: Option<String>,
    pub status_code: Option<u16>,
    pub backtrace: Option<Backtrace>,
}

A serializable error with logging support.

Fields

action: String

Typically starts with a verb.

Will be displayed as:

Failed to {action}

Example: deserialize object

message: String

Example: Object is not valid.

domain: Option<String>

A concise description of the domain in which this occurred:

Will be displayed as:

A {domain} error occurred

Example: serialization

status_code: Option<u16>

An HTTP status code.

Will be displayed as:

A {status_code} error occurred

Example: 404

backtrace: Option<Backtrace>

Backtrace

Implementations

impl Error

pub fn display(&self) -> String

Multiline string representation of the error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Default for Error

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Error

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Serialize for Error

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
