Struct ScopeId 

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

Implementations

impl ScopeId

pub fn new() -> Self

pub fn from_u128(v: u128) -> Self

Deterministic constructor for tests/fixtures and hosts that need a stable, reproducible id (e.g. derived from an external key) rather than Ulid::new()’s wall-clock-derived randomness. The committed FORMAT.md fixture (tests/format_fixture.rs) relies on this for byte-stable ids across format-version checks.

pub fn as_u128(self) -> u128

The id’s raw 128-bit value, inverse of from_u128.

Trait Implementations

impl Clone for ScopeId

fn clone(&self) -> ScopeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScopeId

impl Debug for ScopeId

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

Formats the value using the given formatter.

impl Default for ScopeId

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ScopeId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ScopeId

Canonical Crockford base32 ULID string form (26 chars), delegating to ulid::Ulid’s Display. Round-trips through FromStr.

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

Formats the value using the given formatter.

impl Eq for ScopeId

impl FromStr for ScopeId

Parses the canonical ULID string form produced by Display.

type Err = DecodeError

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 ScopeId

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 ScopeId

fn cmp(&self, other: &ScopeId) -> 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 ScopeId

fn eq(&self, other: &ScopeId) -> 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 ScopeId

fn partial_cmp(&self, other: &ScopeId) -> 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 ScopeId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
