Enum AggregateExecError 

#[non_exhaustive]
pub enum AggregateExecError {
    UnsupportedGroupByExpressionCount {
        count: usize,
    },
    UnsupportedGroupByExpressionType {
        data_type: ColumnType,
    },
}

Errors returned when an aggregate proof plan cannot be constructed.

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.

UnsupportedGroupByExpressionCount

Grouping and deduplication support at most one expression.

Fields

count: usize

Number of grouping expressions found.

UnsupportedGroupByExpressionType

The grouping expression has a datatype for which uniqueness cannot be proven.

Fields

data_type: ColumnType

Unsupported grouping datatype.

impl Eq for AggregateExecError

impl Error for AggregateExecError

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 AggregateExecError

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 PartialEq for AggregateExecError

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

Equality operator ==.

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

Inequality operator !=.
