Struct StableKey 

pub struct StableKey(/* private fields */);

StableKey

Canonical durable logical allocation identity.

A stable key names the logical store, not the current storage backend or MemoryManager ID. Once committed, the key is permanently bound to its physical allocation slot; changing the key declares a new logical store.

Implementations

impl StableKey

pub fn parse(value: impl AsRef<str>) -> Result<Self, StableKeyError>

Parse and validate a canonical stable key string.

Keys are bounded lowercase ASCII dot-separated names ending in a nonzero .vN suffix.

pub fn as_str(&self) -> &str

Borrow the canonical stable-key string.

pub fn into_string(self) -> String

Consume the key and return the canonical stable-key string.

Trait Implementations

impl AsRef<str> for StableKey

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for StableKey

fn clone(&self) -> StableKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StableKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StableKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StableKey

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

Formats the value using the given formatter.

impl FromStr for StableKey

type Err = StableKeyError

The associated error which can be returned from parsing.

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

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

impl Hash for StableKey

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 StableKey

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

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StableKey

fn eq(&self, other: &StableKey) -> 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 PartialOrd for StableKey

fn partial_cmp(&self, other: &StableKey) -> 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 Serialize for StableKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Validate for StableKey

type Error = StableKeyError

Validation error for this DTO.

fn validate(&self) -> Result<(), Self::Error>

Validate this value’s domain invariants.

impl Eq for StableKey

impl StructuralPartialEq for StableKey
