Trait Implementations

impl Arbitrary for PartitionId

type Parameters = <i32 as Arbitrary>::Parameters

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = TupleUnion<((u32, Arc<Map<<i32 as Arbitrary>::Strategy, fn(_: i32) -> Self>>), (u32, Arc<fn() -> Self>))>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for PartitionId

fn clone(&self) -> PartitionId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Codec for PartitionId

fn codec_name() -> String

Name of the codec.

fn encode<B: BufMut>(&self, buf: &mut B)

Encode a key or value for permanent storage.

fn decode<'a>(buf: &'a [u8]) -> Result<Self, String>

Decode a key or value previous encoded with this codec’s Codec::encode.

impl Display for PartitionId

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

Formats the value using the given formatter.

impl From<&'_ PartitionId> for Option<String>

fn from(pid: &PartitionId) -> Option<String>

impl FromStr for PartitionId

type Err = Error

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

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

impl Hash for PartitionId

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

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<PartitionId> for PartitionId

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<PartitionId> for PartitionId

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

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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