Enum ApiError 

pub enum ApiError {
    NotFound,
    BadRequest(String),
    VersionMismatch {
        current: u64,
        sent: String,
    },
    Db(Error),
    Json(Error),
    Internal(String),
}

Every error the sim’s HTTP handlers can raise.

Variants

NotFound

Resource absent. Produces 404.

BadRequest(String)

Client-supplied input failed validation. Produces 400.

VersionMismatch

If-Match version did not match the current row’s version. Produces 409.

Fields

current: u64

Server-side current version (what the client should have sent).

sent: String

Raw If-Match value as received (without RFC-7232 quotes).

Db(Error)

Underlying SQLite error. Produces 500 (opaque body). The detailed error is logged via tracing::error! server-side.

Json(Error)

Underlying JSON error. Produces 400 (request-side) or 500 (response-side). Handler code decides via ApiError::BadRequest which side of the boundary the error came from; this variant is the escape hatch for library-level Serde failures.

Internal(String)

Internal invariant violation (e.g. schema load returned Err, or a unicode assumption about label JSON failed). Produces 500 with an opaque body.

Implementations

impl ApiError

pub fn status(&self) -> StatusCode

HTTP status for this error.

pub fn kind(&self) -> &'static str

Stable error-kind string for the JSON body.

Trait Implementations

impl Debug for ApiError

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

Formats the value using the given formatter.

impl Display for ApiError

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

Formats the value using the given formatter.

impl Error for ApiError

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.
