Enum IndexSpecError 

#[non_exhaustive]
pub enum IndexSpecError {
    EmptyColumn,
    EmptyEntityColumn {
        position: usize,
    },
    DuplicateEntityColumn {
        column: String,

Structural errors in an IndexSpec.

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.

EmptyColumn

The registered index column is empty.

EmptyEntityColumn

An entity column is empty.

Fields

position: usize

Zero-based position of the empty entity column.

DuplicateEntityColumn

An entity column is repeated.

Fields

column: String

Repeated entity column name.

EntityColumnMatchesIndex

An entity column is also the ordered index column.

Fields

column: String

Conflicting column name.

ZeroTimeIndexGranularity

A timestamp index granularity was constructed directly with a zero width.

Trait Implementations

impl Debug for IndexSpecError

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

Formats the value using the given formatter.

impl Display for IndexSpecError

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

Formats the value using the given formatter.

impl Eq for IndexSpecError

impl Error for IndexSpecError

where Self: Debug + Display,

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 ErrorCompat for IndexSpecError

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<IndexSpecError> for CreateTableError

where IndexSpecError: Into<IndexSpecError>,

fn from(error: IndexSpecError) -> Self

Converts to this type from the input type.

impl PartialEq for IndexSpecError

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

Equality operator ==.

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

Inequality operator !=.
