Enum Error 

#[non_exhaustive]
pub enum Error {
    Validation {
        field: String,
        msg: String,
    },
    NotFound {
        msg: String,
    },
    Conflict {
        msg: String,
    },
    RateLimited {
        retry_after_secs: u32,
    },
    Storage {
        msg: String,
    },
    Internal {
        msg: String,
    },
}

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.

Validation

Operator-supplied input was wrong. 400.

Fields

field: String

msg: String

NotFound

Resource not found. 404.

Fields

msg: String

Conflict

Conflict (dedupe, concurrent modification, busy lock). 409.

Fields

msg: String

RateLimited

Rate-limited upstream — operator should back off. 429.

Fields

retry_after_secs: u32

Storage

Anything else from the storage layer. 500.

Fields

msg: String

Internal

Catch-all bug / panic-equivalent. 500.

Fields

msg: String

Implementations

impl Error

pub fn validation(field: impl Into<String>, msg: impl Into<String>) -> Self

pub fn not_found(msg: impl Into<String>) -> Self

pub fn internal(msg: impl Into<String>) -> Self

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<StorageError> for Error

fn from(e: StorageError) -> Self

Converts to this type from the input type.

impl IntoResponse for Error

fn into_response(self) -> Response

Create a response.

impl Serialize for Error

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
