Struct DataError 

pub struct DataError { /* private fields */ }

Error : DataError (Kind: JsonData)

Implementations

impl DataError

pub const kind: ErrorKind = JsonData

Represents a categorized error kind

pub fn new() -> Self

Creates a new Error instance.

Arguments

• code - A numerical status or error code (e.g., HTTP status code).
• class - A string representing the error category or type (e.g., “ValidationError”).
• message - A human-readable error message.
• details - Additional error details stored in a key-value map, using serde_value::Value.

Returns

A new instance of Error.

pub fn code(&self) -> u16

Numerical status or error code (e.g., HTTP status code).

pub fn with_code(self, code: u16) -> Self

Adds a custom status code to the error.

pub fn message(&self) -> String

Returns the error message as a String.

pub fn with_message(self, message: String) -> Self

Adds a custom message to the error.

pub fn details(&self) -> BTreeMap<String, Value>

Returns a clone of the details map.

pub fn with_details(self, details: BTreeMap<String, Value>) -> Self

Adds a structured map of additional error details.

pub fn class(&self) -> String

Returns the error class as a String.

Trait Implementations

impl Clone for DataError

fn clone(&self) -> DataError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataError

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

Formats the value using the given formatter.

impl Display for DataError

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

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 From<DataError> for Error

fn from(err: DataError) -> Error

Converts to this type from the input type.
