Variants

SqliteFailure(Error, Option<String>)

An error from an underlying SQLite call.

SqliteSingleThreadedMode

Error reported when attempting to open a connection when SQLite was configured to allow single-threaded use only.

FromSqlConversionFailure(Box<Error + Send + Sync>)

An error case available for implementors of the FromSql trait.

Utf8Error(Utf8Error)

Error converting a string to UTF-8.

NulError(NulError)

Error converting a string to a C-compatible string because it contained an embedded nul.

InvalidParameterName(String)

Error when using SQL named parameters and passing a parameter name not present in the SQL.

InvalidPath(PathBuf)

Error converting a file path to a string.

ExecuteReturnedResults

Error returned when an execute call returns rowss.

QueryReturnedNoRows

Error when a query that was expected to return at least one row (e.g., for query_row) did not return any.

GetFromStaleRow

Error when trying to access a Row after stepping past it. See the discussion on the Rows type for more details.

InvalidColumnIndex(c_int)

Error when the value of a particular column is requested, but the index is out of range for the statement.

InvalidColumnType

Error when the value of a particular column is requested, but the type of the result in that column cannot be converted to the requested Rust type.
