Struct CallbackError 

pub struct CallbackError { /* private fields */ }

Common error information for prepare lifecycle callbacks.

This keeps the error type name together with the message so callers can classify failures without depending on fragile string matching.

Examples

use qubit_dcl::double_checked::CallbackError;

let prepare_error = CallbackError::with_type("prepare", "Resource is locked");
assert_eq!(prepare_error.callback_type(), Some("prepare"));
println!("prepare_error = {:?}", prepare_error);

Implementations

impl CallbackError

pub fn from_display<T: Display>(error: T) -> Self

Builds a callback error without type metadata.

pub fn with_type<T: Display>(source_type: &'static str, error: T) -> Self

pub fn message(&self) -> &str

Returns the raw message.

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

Returns the callback type label, when available.

pub fn is_typed(&self) -> bool

Returns whether the callback type label is set.
