Enum HaCloneType 

#[non_exhaustive]
pub enum HaCloneType {
    Blocking,
    Redo,
    Page,
    Hybrid,
    MultiTask,
    Restart,
    Unknown,
}

Clone-transfer type the source engine should perform.

Mirrors enum Ha_clone_type in mysql-server/sql/handler.h.

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.

Blocking

HA_CLONE_BLOCKING: serialised copy (write operations must block).

Redo

HA_CLONE_REDO: archive redo log to support concurrent DML.

Page

HA_CLONE_PAGE: page-tracked incremental.

Hybrid

HA_CLONE_HYBRID: page tracking + redo (currently InnoDB).

MultiTask

HA_CLONE_MULTI_TASK: multiple worker threads.

Restart

HA_CLONE_RESTART: restart after network failure.

Unknown

Forward-compatible fallback.

Implementations

impl HaCloneType

pub const fn from_raw(value: usize) -> Self

Decode the C enum Ha_clone_type value (a size_t upstream).

Trait Implementations

impl Clone for HaCloneType

fn clone(&self) -> HaCloneType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HaCloneType

impl Debug for HaCloneType

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

Formats the value using the given formatter.

impl Eq for HaCloneType

impl PartialEq for HaCloneType

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