Struct Attested 

pub struct Attested<T, Via> { /* private fields */ }

A machine value with attached typed provenance for how it was produced.

Statum uses this wrapper for attested transition routes such as capture_and_attest() and generated from_*() binders. The public surface exposes the wrapped machine and the route type, but construction stays on the macro-generated path so ordinary callers cannot forge attestation accidentally.

Implementations

impl<T, Via> Attested<T, Via>

pub fn into_inner(self) -> T

Consumes the wrapper and returns the attested inner value.

pub fn as_ref(&self) -> &T

Borrows the attested inner value.

pub fn map_inner<U>(self, f: impl FnOnce(T) -> U) -> Attested<U, Via>

Maps the inner value while preserving the attested route marker.

Trait Implementations

impl<T, Via> AsRef<T> for Attested<T, Via>

fn as_ref(&self) -> &T

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

impl<T: Clone, Via: Clone> Clone for Attested<T, Via>

fn clone(&self) -> Attested<T, Via>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug, Via: Debug> Debug for Attested<T, Via>

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

Formats the value using the given formatter.

impl<T: Hash, Via: Hash> Hash for Attested<T, Via>

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<T: Ord, Via: Ord> Ord for Attested<T, Via>

fn cmp(&self, other: &Attested<T, Via>) -> 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<T: PartialEq, Via: PartialEq> PartialEq for Attested<T, Via>

fn eq(&self, other: &Attested<T, Via>) -> 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<T: PartialOrd, Via: PartialOrd> PartialOrd for Attested<T, Via>

fn partial_cmp(&self, other: &Attested<T, Via>) -> 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.
