Enum DbError 

pub enum DbError {
    Query(Error),
    Migration(MigrateError),
    Io(Error),
    InvalidData {
        entity: &'static str,
        reason: String,
    },
    InvalidStatus {
        entity: &'static str,
        value: String,
    },
    QueryContext {
        operation: &'static str,
        source: Error,
    },
}

Typed error returned by database operations.

Wraps the underlying SQLx, migration, and I/O failures so callers can distinguish error categories without parsing opaque strings.

Variants

Query(Error)

A SQL query or connection-pool operation failed.

Migration(MigrateError)

An embedded schema migration failed during database open.

Io(Error)

A filesystem operation failed, such as creating the database directory.

InvalidData

Caller-provided or persisted data violated a domain invariant.

Fields

entity: &'static str

Persistence entity whose data failed validation.

reason: String

Human-readable invariant violation.

InvalidStatus

A persisted lifecycle value could not be decoded by its owning adapter.

Fields

entity: &'static str

Persistence entity whose status failed validation.

value: String

Unrecognized stored or caller-provided value.

QueryContext

A query failed during a named persistence operation.

Fields

operation: &'static str

Stable semantic label for the failed operation.

source: Error

Underlying SQLx failure.

Trait Implementations

impl Debug for DbError

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

Formats the value using the given formatter.

impl Display for DbError

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

Formats the value using the given formatter.

impl Error for DbError

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.
