Enum TableError 

#[non_exhaustive]
pub enum TableError {
    NoBatches,
    ColumnCount {
        expected: usize,
        found: usize,
    },
    ColumnMismatch {
        column: usize,
    },
    NoSuchColumn(usize),
}

Why a batch could not be added, or a column setting applied.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoBatches

No batch was given, so there is no schema.

ColumnCount

The batch has a different number of columns.

Fields

expected: usize

Columns in the table.

found: usize

Columns in the batch.

ColumnMismatch

The batch’s column at this index has another data type.

Fields

column: usize

Index of the first differing column.

NoSuchColumn(usize)

There is no column at this index.

Trait Implementations

impl Clone for TableError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TableError

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

Formats the value using the given formatter.

impl Display for TableError

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

Formats the value using the given formatter.

impl Eq for TableError

impl Error for TableError

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

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

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 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 PartialEq for TableError

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

Equality operator ==.

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

Inequality operator !=.
