#[non_exhaustive]
pub enum FromSqlError { InvalidType, OutOfRange(i64), InvalidBlobSize { expected_size: usize, blob_size: usize, }, Other(Box<dyn Error + Send + Sync + 'static>), }
Expand description

Enum listing possible errors from FromSql trait.

Variants (Non-exhaustive)§

This enum is marked as 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

Fields

§expected_size: usize

The expected size of the blob.

§blob_size: usize

The actual size of the blob that was returned.

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

§

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

An error case available for implementors of the FromSql trait.

1.0.0 · source§

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. Read more
source§

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.

source§

fn from(err: FromSqlError) -> Error

Converts to this type from the input type.
source§

impl PartialEq for FromSqlError

source§

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

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

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.
