Enum BoundsType 

#[repr(i32)]
pub enum BoundsType {
    Unspecified = 0,
    Rows = 1,
    Range = 2,
}

Variants

Unspecified = 0

Unspecified. Producers must set one of the defined bounds type.

Rows = 1

Bounds are physical row offsets in the declared ordering in sorts. If no ordering is declared, no order is guaranteed.

Range = 2

Bounds are value offsets from the current row’s ordering value. This bounds type requires exactly one ordering expression if Preceding or Following is used. Preceding moves toward values earlier in the declared ordering in sorts; Following moves toward values later in the declared ordering in sorts. Bounds are inclusive.

Implementations

impl BoundsType

pub const fn is_valid(value: i32) -> bool

Returns true if value is a variant of BoundsType.

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

👎Deprecated:

Use the TryFrom<i32> implementation instead

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

impl BoundsType

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<BoundsType>

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

Trait Implementations

impl Clone for BoundsType

fn clone(&self) -> BoundsType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BoundsType

impl Debug for BoundsType

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

Formats the value using the given formatter.

impl Default for BoundsType

fn default() -> BoundsType

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BoundsType

fn deserialize<D>( deserializer: D, ) -> Result<BoundsType, <D as Deserializer<'de>>::Error>

impl Eq for BoundsType

impl Hash for BoundsType

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

impl StructuralPartialEq for BoundsType

impl TryFrom<i32> for BoundsType

type Error = UnknownEnumValue

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

Performs the conversion.
