Struct mz_persist_client::ShardId

pub struct ShardId(pub(crate) [u8; 16]);

An opaque identifier for a persist durable TVC (aka shard).

The std::string::ToString::to_string format of this may be stored durably or otherwise used as an interchange format. It can be parsed back using str::parse or std::str::FromStr::from_str.

Implementations

impl ShardId

pub fn new() -> Self

Returns a random ShardId that is reasonably likely to have never been generated before.

Trait Implementations

impl Arbitrary for ShardId

type Parameters = <[u8; 16] as Arbitrary>::Parameters

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

type Strategy = Map<<[u8; 16] as Arbitrary>::Strategy, fn(_: [u8; 16]) -> ShardId>

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 ShardId

fn clone(&self) -> ShardId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Codec for ShardId

type Schema = ShardIdSchema

The type of the associated schema for Self.

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 Debug for ShardId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ShardId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ShardId

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

Formats the value using the given formatter.

impl From<ShardId> for String

fn from(shard_id: ShardId) -> Self

Converts to this type from the input type.

impl FromStr for ShardId

type Err = String

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 Hash for ShardId

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 ShardId

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ShardId

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ShardId

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

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

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

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

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.

impl RustType<String> for ShardId

fn into_proto(&self) -> String

Convert a Self into a Proto value.

fn from_proto(proto: String) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.
