Enum BulkAccess 

#[non_exhaustive]
pub enum BulkAccess {
    Batched,
    PerRow,
}

Whether the engine batches the rows of a multi-row UPDATE or DELETE itself, or lets MySQL drive the statement one row at a time.

MySQL’s start_bulk_update / start_bulk_delete encode this as an inverted bool (true means “bulk not used”); this enum exists so engine code never has to reason about that inversion.

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.

Batched

Engine batches the rows; MySQL routes them through the bulk path (bulk_update_row + exec_bulk_update for updates, end_bulk_delete for deletes). Maps to C++ false.

PerRow

Engine declines batching; MySQL performs the statement row by row via update_row / delete_row. Maps to C++ true, the handler-base default.

Implementations

impl BulkAccess

pub fn to_mysql_bool(self) -> bool

The MySQL bool expected by start_bulk_update / start_bulk_delete: true when the engine declines batching (normal per-row operation), matching the inverted handler-base contract.

Trait Implementations

impl Clone for BulkAccess

fn clone(&self) -> BulkAccess

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BulkAccess

impl Debug for BulkAccess

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

Formats the value using the given formatter.

impl Eq for BulkAccess

impl PartialEq for BulkAccess

fn eq(&self, other: &BulkAccess) -> 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.
