Struct Error 

pub struct Error(/* private fields */);

A failure answered as the REST API would answer it.

Wraps the postrust_core::Error the REST pipeline reports with, so its status and body come from the same table: a database error by its SQLSTATE (23505 is 409, 42501 a missing grant is 401, P0001 a bare RAISE is 400), a refusal raised with sqlstate 'PGRST' with the status, headers and body the function wrote, a broken connection as 503.

The database’s own account of an error – its message, detail and hint, which name constraints and columns – is passed through only where the REST API would pass it through: in compatibility mode (PGRST_COMPAT_MODE) or with PGRST_DEBUG. Compatibility mode is the server’s configuration, which an error converted by ? has no way to reach, so it is applied on the way out by the routers given to Builder::nest. A router served some other way gets the sanitised body.

Implementations

impl Error

pub fn status(&self) -> StatusCode

The status this is answered with.

pub fn as_core(&self) -> &Error

The error as the REST pipeline reports it.

pub fn into_core(self) -> Error

The error as the REST pipeline reports it, by value.

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<DbError> for Error

fn from(error: DbError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

Through the driver-neutral DbError, as the REST pipeline’s own sqlx errors go: a statement PostgreSQL refused keeps its SQLSTATE, a connection that broke or could not be had from the pool is the database being unavailable, anything else is internal.

fn from(error: Error) -> Self

Converts to this type from the input type.

impl IntoResponse for Error

fn into_response(self) -> Response

Create a response.
