Enum DiffMode 

#[repr(i32)]
pub enum DiffMode {
    DiffAuto = 0,
    DiffChangefeed = 1,
    DiffReplay = 2,
    DiffVersionScan = 3,
}

Which data path served (or should serve) a team diff. Additive enum: AUTO is the wire default (tag 0) so existing callers are unchanged. See issue #838.

Variants

DiffAuto = 0

changefeed if the window is fully retained, else version-scan head + changefeed tail

DiffChangefeed = 1

force the windowed durable-changefeed scan

DiffReplay = 2

alias of changefeed (replay_committed-backed); reserved for future divergence

DiffVersionScan = 3

force the #724 full-version-scan oracle path

Implementations

impl DiffMode

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of DiffMode.

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

👎Deprecated:

Use the TryFrom<i32> implementation instead

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

impl DiffMode

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.

Trait Implementations

impl Clone for DiffMode

fn clone(&self) -> DiffMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DiffMode

impl Debug for DiffMode

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

Formats the value using the given formatter.

impl Default for DiffMode

fn default() -> DiffMode

Returns the “default value” for a type.

impl Eq for DiffMode

impl From<DiffMode> for i32

fn from(value: DiffMode) -> i32

Converts to this type from the input type.

impl Hash for DiffMode

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 DiffMode

fn cmp(&self, other: &DiffMode) -> 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.

impl PartialEq for DiffMode

fn eq(&self, other: &DiffMode) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for DiffMode

fn partial_cmp(&self, other: &DiffMode) -> 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 StructuralPartialEq for DiffMode

impl TryFrom<i32> for DiffMode

type Error = UnknownEnumValue

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

Performs the conversion.
