Enum SimError 

#[non_exhaustive]
pub enum SimError {
    Io(Error),
    Bind {
        addr: String,
        source: Error,
    },
    Api(ApiError),
}

The error type returned by the simulator crate’s public library API.

Distinct from ApiError (which is the per-request HTTP error type that implements IntoResponse). SimError is what run, run_with_listener, and prepare_state return; it composes the underlying typed variants (I/O, bind failures, ApiError) so callers can pattern-match if they need to and so the reposix-sim binary can adapt to anyhow::Error for free via the blanket From<E: std::error::Error + Send + Sync + 'static> impl on anyhow::Error.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

Generic I/O failure — covers axum::serve (which returns io::Error), TcpListener::local_addr, and any unspecified I/O during startup.

Bind

Failed to bind the configured listener address.

Fields

addr: String

Address that failed to bind, for operator diagnostics.

source: Error

Underlying I/O error from TcpListener::bind.

Api(ApiError)

An ApiError surfaced from internal helpers (db::open_db, seed::load_seed). Wrapped instead of flattened so future pattern-matching can recover the original variant.

Trait Implementations

impl Debug for SimError

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

Formats the value using the given formatter.

impl Display for SimError

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

Formats the value using the given formatter.

impl Error for SimError

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 From<ApiError> for SimError

fn from(source: ApiError) -> Self

Converts to this type from the input type.

impl From<Error> for SimError

fn from(source: Error) -> Self
