Errors from operations on tables.

Variants

UnionIncompatibleSchemas

Errors related to unioning tables with incompatible schemas.

Fields

correct_schema: Vec<ColumnField>

The correct data type

actual_schema: Vec<ColumnField>

The schema of the table that caused the error

JoinWithDifferentNumberOfColumns

Errors related to joining tables with different numbers of columns.

Fields

left_num_columns: usize

The number of columns in the left-hand table

right_num_columns: usize

The number of columns in the right-hand table

JoinIncompatibleTypes

Errors related to joining tables on columns with incompatible types.

Fields

left_type: ColumnType

The left-hand side data type

right_type: ColumnType

The right-hand side data type

ColumnDoesNotExist

Errors related to a column that does not exist in a table.

Fields

column_ident: Ident

The nonexistent column identifier

DuplicateColumn

Errors related to duplicate columns in a table.

ColumnOperationError

Errors due to bad column operations.

Fields

source: ColumnOperationError

The underlying ColumnOperationError

ColumnIndexOutOfBounds

Errors related to column index out of bounds.

Fields

column_index: usize

The column index that is out of bounds

Trait Implementations

impl Debug for TableOperationError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TableOperationError

fn fmt(&self, __snafu_display_formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for TableOperationError

where Self: Debug + Display,

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl ErrorCompat for TableOperationError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<ColumnOperationError> for TableOperationError

fn from(error: ColumnOperationError) -> Self

Converts to this type from the input type.

impl PartialEq for TableOperationError

fn eq(&self, other: &TableOperationError) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
