[−][src]Enum rusqlite::Error
Enum listing possible errors from rusqlite.
Variants (Non-exhaustive)
An error from an underlying SQLite call.
Error reported when attempting to open a connection when SQLite was configured to allow single-threaded use only.
Error when the value of a particular column is requested, but it cannot be converted to the requested Rust type.
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.
Error returned when an execute
call returns rows.
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.
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.
Error returned by functions::Context::get
when the function argument
cannot be converted to the requested type.
Error returned by vtab::Values::get
when the filter argument cannot
be converted to the requested type.
An error case available for implementors of custom user functions (e.g.,
create_scalar_function
).
Error available for the implementors of the ToSql
trait.
Error when the SQL is not a SELECT
, is not read-only.
ModuleError(String)
An error case available for implementors of custom modules (e.g.,
create_module
).
An unwinding panic occurs in an UDF (user-defined function).
An error returned when Context::get_aux
attempts to retrieve data
of a different type than what had been stored using Context::set_aux
.
Error when the SQL contains multiple statements.
Error when the number of bound parameters does not match the number of
parameters in the query. The first usize
is how many parameters were
given, the 2nd is how many were expected.
Returned from various functions in the Blob IO positional API. For
example, Blob::raw_read_at_exact
will return it if the blob has insufficient data.

to allow use of get_raw(…).as_…()?
in callbacks that take Error
.
