Trait Implementations

impl Clone for AdaptiveParallelismStrategy

fn clone(&self) -> AdaptiveParallelismStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AdaptiveParallelismStrategy

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

Formats the value using the given formatter.

impl Default for AdaptiveParallelismStrategy

fn default() -> AdaptiveParallelismStrategy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AdaptiveParallelismStrategy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AdaptiveParallelismStrategy

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

Formats the value using the given formatter.

impl From<AdaptiveParallelismStrategy> for String

fn from(val: AdaptiveParallelismStrategy) -> Self

Converts to this type from the input type.

impl FromStr for AdaptiveParallelismStrategy

type Err = ParallelismStrategyParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl ParamValue for AdaptiveParallelismStrategy

type Borrowed<'a> = AdaptiveParallelismStrategy

impl PartialEq for AdaptiveParallelismStrategy

fn eq(&self, other: &AdaptiveParallelismStrategy) -> 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 Serialize for AdaptiveParallelismStrategy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for AdaptiveParallelismStrategy
