Struct TraceableBox 

pub struct TraceableBox(pub Box<dyn TraceableError + Send + Sync + 'static>);

A concrete, sized encapsulation of a dynamic TraceableError trait object.

This wrapper acts as a type-erased boundary. It enables seamless bidirectional ? operator compatibility across dynamic crate boundaries, allowing concrete error enums (via thiserror) and untyped conduits (anyhow) to nest inside each other without losing causal tracing history.

Example

use traceable_error::{TraceableError, TraceableBox};

fn produce_anyhow() -> anyhow::Result<()> {
    Err(anyhow::anyhow!("root failure"))
}

// Seamlessly converts the anyhow::Error into a TraceableBox trait object via ?
fn consume_box() -> Result<(), TraceableBox> {
    produce_anyhow()?;
    Ok(())
}

Trait Implementations

impl Debug for TraceableBox

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

Formats the value using the given formatter.

impl Display for TraceableBox

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

Formats the value using the given formatter.

impl Error for TraceableBox

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<E: TraceableError + Send + Sync + 'static> From<E> for TraceableBox

fn from(err: E) -> Self

Converts to this type from the input type.
