Enum DbError 

pub enum DbError {
    CorruptDatabase(String),
    MissingTable(String),
    InvalidQuery(String),
    DatabaseLocked,
    NoResults,
}

Database errors.

Variants

CorruptDatabase(String)

Database file is corrupted.

MissingTable(String)

Required table is missing.

InvalidQuery(String)

Query syntax error.

DatabaseLocked

Database is locked by another process.

NoResults

Query returned no results.

Implementations

impl DbError

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

Get a user-friendly recovery suggestion.

pub fn log_message(&self) -> String

Get a sanitized error message suitable for logging.

Trait Implementations

impl Clone for DbError

fn clone(&self) -> DbError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 ErrorCode for DbError

fn error_code(&self) -> &'static str

Get a unique error code for this error type.

impl PartialEq for DbError

fn eq(&self, other: &DbError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
