Enum listing possible errors from rusqlite.

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(usize, Type, Box<Error + Send + Sync>)

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

IntegralValueOutOfRange(c_int, i64)

Error when SQLite gives us an integral value outside the range of the requested type (e.g., trying to get the value 1000 into a u8). The associated c_int is the column index, and the associated i64 is the value returned by SQLite.

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 rows.

QueryReturnedNoRows

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

InvalidColumnIndex(c_int)

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

InvalidColumnName(String)

Error when the value of a named column is requested, but no column matches the name for the statement.

InvalidColumnType(c_int, Type)

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.

StatementChangedRows(c_int)

Error when a query that was expected to insert one row did not insert any or insert many.

ToSqlConversionFailure(Box<Error + Send + Sync>)

Error available for the implementors of the ToSql trait.
