Struct CoreError 

#[non_exhaustive]
pub struct CoreError { /* private fields */ }

Structured core error with a stable code and human-friendly message.

use daedalus_core::errors::{CoreError, CoreErrorCode};
let err = CoreError::new(CoreErrorCode::InvalidId, "bad id");
assert_eq!(err.code(), CoreErrorCode::InvalidId);
assert_eq!(err.message(), "bad id");

Implementations

impl CoreError

pub fn new(code: CoreErrorCode, message: impl Into<String>) -> Self

pub fn code(&self) -> CoreErrorCode

pub fn message(&self) -> &str

pub fn with_context(self, context: impl Into<String>) -> Self

Attach additional context while keeping the same code.

Trait Implementations

impl Clone for CoreError

fn clone(&self) -> CoreError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoreError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CoreError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CoreError

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

Formats the value using the given formatter.

impl Error for CoreError

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 CoreError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
