Indicates whether the fragment contains some special kind of nodes.

Variants

FragmentUnspecified = 0

Source = 1

Mview = 2

Sink = 4

Now = 8

TODO: Remove this and insert a BarrierRecv instead.

StreamScan = 16

Include StreamScan and StreamCdcScan

BarrierRecv = 32

Values = 64

Dml = 128

CdcFilter = 256

SourceScan = 1_024

SnapshotBackfillStreamScan = 2_048

FsFetch = 4_096

Note: this flag is not available in old fragments, so only suitable for debugging purpose.

CrossDbSnapshotBackfillStreamScan = 8_192

Implementations

impl FragmentTypeFlag

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of FragmentTypeFlag.

pub fn from_i32(value: i32) -> Option<FragmentTypeFlag>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a FragmentTypeFlag, or None if value is not a valid variant.

impl FragmentTypeFlag

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

impl FragmentTypeFlag

pub fn backfill_rate_limit_fragments() -> i32

Fragments that may be affected by BACKFILL_RATE_LIMIT.

pub fn source_rate_limit_fragments() -> i32

Fragments that may be affected by SOURCE_RATE_LIMIT. Note: for FsFetch, old fragments don’t have this flag set, so don’t use this to check.

pub fn sink_rate_limit_fragments() -> i32

Fragments that may be affected by BACKFILL_RATE_LIMIT.

pub fn rate_limit_fragments() -> i32

Note: this doesn’t include FsFetch created in old versions.

pub fn dml_rate_limit_fragments() -> i32

Trait Implementations

impl Clone for FragmentTypeFlag

fn clone(&self) -> FragmentTypeFlag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FragmentTypeFlag

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

Formats the value using the given formatter.

impl Default for FragmentTypeFlag

fn default() -> FragmentTypeFlag

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FragmentTypeFlag

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<FragmentTypeFlag> for i32

fn from(value: FragmentTypeFlag) -> i32

Converts to this type from the input type.

impl Hash for FragmentTypeFlag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for FragmentTypeFlag

fn cmp(&self, other: &FragmentTypeFlag) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FragmentTypeFlag

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

impl PartialOrd for FragmentTypeFlag

fn partial_cmp(&self, other: &FragmentTypeFlag) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for FragmentTypeFlag

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<i32> for FragmentTypeFlag

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<FragmentTypeFlag, UnknownEnumValue>

Performs the conversion.

impl Copy for FragmentTypeFlag
