Enum DataError 

pub enum DataError {
    Database(DbErr),
    Sqlx(Error),
    Pagination(PaginationError),
}

The error returned by the high-level data layer.

One database-error variant preserves the upstream SeaORM error (SeaORM’s DbErr is already contextual — it distinguishes connection, query, record not found, and constraint failures). A separate variant preserves raw SQLx errors for the escape-hatch path. Pagination validation failures are a distinct typed enum so they never collide with a database failure.

Variants

Database(DbErr)

A SeaORM query, mutation, or transaction returned a database error.

Sqlx(Error)

A raw SQLx operation (the escape hatch) returned a database error.

Pagination(PaginationError)

A pagination argument was invalid (zero is not a valid page or per-page size).

Implementations

impl DataError

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

The stable, machine-readable error identifier (for structured logging and arc doctor-style diagnostics). Stable strings, never the dynamic message — callers may match on these.

Trait Implementations

impl Debug for DataError

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

Formats the value using the given formatter.

impl Display for DataError

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

Formats the value using the given formatter.

impl Error for DataError

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.
