Struct txn_types::WriteBatchFlags

pub struct WriteBatchFlags {

Fields

bits: u64

Implementations

impl WriteBatchFlags

pub const ONE_PC: WriteBatchFlags

Indicates this request is from a 1PC transaction. It helps CDC recognize 1PC transactions and handle them correctly.

pub const STALE_READ: WriteBatchFlags

Indicates this request is from a stale read-only transaction.

pub const fn empty() -> WriteBatchFlags

Returns an empty set of flags

pub const fn all() -> WriteBatchFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u64

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u64) -> Option<WriteBatchFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u64) -> WriteBatchFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u64) -> WriteBatchFlags

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: WriteBatchFlags) -> bool

Returns true if there are flags common to both self and other.

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

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: WriteBatchFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: WriteBatchFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: WriteBatchFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: WriteBatchFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.

impl WriteBatchFlags

pub fn from_bits_check(bits: u64) -> WriteBatchFlags

Convert from underlying bit representation panic if it contains bits that do not correspond to a flag
