Enum DbError 

pub enum DbError {
    Connection(String),
    Query(String),
    Transaction(String),
    Pool(String),
    RowMapping(String),
}

Errors produced by database connection operations.

This enum covers all failure modes across all backends (libsql, rusqlite, postgres). Backend-specific errors are stringified into the appropriate variant.

Variants

Connection(String)

Connection establishment or configuration failure.

Query(String)

SQL execution or query failure.

Transaction(String)

Transaction begin/commit/rollback failure.

Pool(String)

Connection pool exhaustion or management failure.

RowMapping(String)

Row-to-struct mapping failure (type mismatch, missing column).

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.

impl From<DbCoreError> for DbError

fn from(e: DbCoreError) -> Self

Converts to this type from the input type.
