Struct HtonFlags 

#[non_exhaustive]
pub struct HtonFlags(/* private fields */);

A set of handlerton flags (the HTON_* bits from sql/handler.h).

Returned from Handlerton::flags. The zero-config engine sets HtonFlags::CAN_RECREATE, which is therefore the trait default; return HtonFlags::NONE to clear it.

use mysql_handler::hton::HtonFlags;

let f = HtonFlags::NONE | HtonFlags::CAN_RECREATE;
assert!(f.contains(HtonFlags::CAN_RECREATE));

Implementations

impl HtonFlags

pub const NONE: Self

No flags set (HTON_NO_FLAGS)

pub const CAN_RECREATE: Self

HTON_CAN_RECREATE: the engine implements TRUNCATE by recreating the table. The flag the zero-config engine sets today.

pub const fn empty() -> Self

An empty flag set

pub const fn bits(self) -> u32

The raw bits, for handing the set across the FFI boundary

pub const fn contains(self, other: Self) -> bool

Whether every flag in other is set in self

pub const fn union(self, other: Self) -> Self

The union of two flag sets

Trait Implementations

impl BitOr for HtonFlags

type Output = HtonFlags

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl Clone for HtonFlags

fn clone(&self) -> HtonFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HtonFlags

impl Debug for HtonFlags

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

Formats the value using the given formatter.

impl Eq for HtonFlags

impl PartialEq for HtonFlags

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