Enum RowCount 

#[non_exhaustive]
pub enum RowCount {
    RowCountExact(i64),
    RowCountLowerBound(i64),
}

The number of rows modified by the DML statement.

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.

RowCountExact(i64)

Standard DML returns an exact count of rows that were modified.

RowCountLowerBound(i64)

Partitioned DML doesn’t offer exactly-once semantics, so it returns a lower bound of the rows modified.

Implementations

impl RowCount

pub fn from_row_count_exact(value: impl Into<i64>) -> Self

Initializes the enum to the RowCountExact branch.

pub fn from_row_count_lower_bound(value: impl Into<i64>) -> Self

Initializes the enum to the RowCountLowerBound branch.

Trait Implementations

impl Clone for RowCount

fn clone(&self) -> RowCount

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RowCount

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

Formats the value using the given formatter.

impl PartialEq for RowCount

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

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

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

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