[−][src]Enum c3p0_pool_sqlite::rusqlite::Error
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<dyn Error + 'static + Sync + Send>)
Error when the value of a particular column is requested, but it cannot be converted to the requested Rust type.
IntegralValueOutOfRange(usize, 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 usize
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(usize)
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(usize, 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(usize)
Error when a query that was expected to insert one row did not insert any or insert many.
InvalidFunctionParameterType(usize, Type)
Error returned by functions::Context::get
when the function argument
cannot be converted to the requested type.
UserFunctionError(Box<dyn Error + 'static + Sync + Send>)
An error case available for implementors of custom user functions (e.g.,
create_scalar_function
).
ToSqlConversionFailure(Box<dyn Error + 'static + Sync + Send>)
Error available for the implementors of the ToSql
trait.
InvalidQuery
Error when the SQL is not a SELECT
, is not read-only.
UnwindingPanic
GetAuxWrongType
An error returned when Context::get_aux
attempts to retrieve data
of a different type than what had been stored using Context::set_aux
.
