Enum HaStatType 

#[non_exhaustive]
pub enum HaStatType {
    Status,
    Logs,
    Mutex,
}

Which subset of engine status MySQL wants for SHOW ENGINE <name> STATUS.

Mirrors enum ha_stat_type in mysql-server/sql/handler.h. Used as the argument to Handlerton::show_status.

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.

Status

HA_ENGINE_STATUS: SHOW ENGINE <name> STATUS — the engine’s general status block.

Logs

HA_ENGINE_LOGS: SHOW ENGINE <name> LOGS — log-file inventory.

Mutex

HA_ENGINE_MUTEX: SHOW ENGINE <name> MUTEX — mutex / lock statistics.

Implementations

impl HaStatType

pub const fn from_raw(value: u32) -> Self

Decode the C enum ha_stat_type value. Unknown values map to HaStatType::Status so the engine still observes a defined variant.

Trait Implementations

impl Clone for HaStatType

fn clone(&self) -> HaStatType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HaStatType

impl Debug for HaStatType

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

Formats the value using the given formatter.

impl Eq for HaStatType

impl PartialEq for HaStatType

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