Struct ComponentStreamIdentity 

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

A stable, owner-scoped ItemStream namespace token.

This is the durable component-state namespace: it is never derived from a display name, a memory address, or runtime object identity, and it participates in the restart-relevant chunk definition fingerprint alongside the other component revisions.

Implementations

impl ComponentStreamIdentity

pub fn new( value: impl Into<String>, ) -> Result<ComponentStreamIdentity, DefinitionError>

Validates and constructs the token.

Errors

Rejects empty values, values longer than 128 UTF-8 bytes, surrounding whitespace, and control characters.

pub fn as_str(&self) -> &str

Borrows the validated token.

Trait Implementations

impl Clone for ComponentStreamIdentity

fn clone(&self) -> ComponentStreamIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentStreamIdentity

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

Formats the value using the given formatter.

impl Eq for ComponentStreamIdentity

impl Hash for ComponentStreamIdentity

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

where __H: Hasher,

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 ComponentStreamIdentity

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

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ComponentStreamIdentity

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ComponentStreamIdentity

fn partial_cmp(&self, other: &ComponentStreamIdentity) -> 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.
