Struct LoraError 

pub struct LoraError { /* private fields */ }

Public error type at the lora-database boundary.

Construct via Self::from_anyhow (the typical path — the engine uses anyhow::Error internally) or via the From impls for any known concrete error type.

Implementations

impl LoraError

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

pub fn with_source( code: LoraErrorCode, message: impl Into<String>, source: impl Error + Send + Sync + 'static, ) -> Self

pub fn code(&self) -> LoraErrorCode

pub fn message(&self) -> &str

pub fn category(&self) -> LoraErrorCategory

pub fn from_anyhow(err: Error) -> Self

Convert an anyhow::Error from the engine’s internal ?-chains into a typed LoraError. Best-effort: downcasts the chain to any known concrete error type and picks the matching code; falls back to LoraErrorCode::Internal with the original message preserved.

pub fn from_anyhow_ref(err: &Error) -> Self

Borrowed version of Self::from_anyhow. Useful in binding layers that hold &anyhow::Error from a Result::Err capture and don’t want to move the error.

Trait Implementations

impl Debug for LoraError

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

Formats the value using the given formatter.

impl Display for LoraError

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

Formats the value using the given formatter.

impl Error for LoraError

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>)
