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.

🔬This is a nightly-only experimental API. (error_generic_member_access)
Provides type based access to context intended for error reports. Read more

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

Converts to this type from the input type.
This method tests for self and other values to be equal, and is used by ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
