pub enum FromSqlError {

}

Enum listing possible errors from FromSql trait.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidType

Error when an SQLite value is requested, but the type of the result cannot be converted to the requested Rust type.

OutOfRange(i64)

Error when the i64 value returned by SQLite cannot be stored into the requested type.

InvalidBlobSize

Error when the blob result returned by SQLite cannot be stored into the requested type due to a size mismatch.

Fields

expected_size: usize

The expected size of the blob.

blob_size: usize

The actual size of the blob that was returned.

Other(Box<dyn Error + Send + Sync + 'static>)

An error case available for implementors of the FromSql trait.

Trait Implementations

impl Debug for FromSqlError

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

Formats the value using the given formatter.

impl Display for FromSqlError

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

Formats the value using the given formatter.

impl Error for FromSqlError

fn source(&self) -> Option<&(dyn Error + 'static)>

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<FromSqlError> for Error

The conversion isn’t precise, but it’s convenient to have it to allow use of get_raw(…).as_…()? in callbacks that take Error.

fn from(err: FromSqlError) -> Error

Converts to this type from the input type.

impl PartialEq for FromSqlError

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

This method tests for self and other values to be equal, and is used by ==.

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

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