Struct ExecutionRealm 

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

An opaque execution realm token. See Target for why this is a newtype, why the ordinals are wire, and why Debug is hand-written.

Implementations

impl ExecutionRealm

pub const McuAot: Self

Historically assigned 0.

pub const HostStream: Self

Historically assigned 1.

pub const BlutDurable: Self

Historically assigned 2.

pub const KNOWN: [Self; 3]

Every token this version of the crate knows, in ordinal order.

pub const fn token(self) -> u32

pub const fn from_token(token: u32) -> Self

pub const fn is_known(self) -> bool

pub const fn target(self) -> Target

The target a realm lowers to.

Kept as a total function on the realm because the compile-side selection and the decode-side authorization must not be able to disagree; an unknown realm maps to an unknown target rather than to a default, so a forged plan cannot borrow the host’s target by being out of range.

Trait Implementations

impl Clone for ExecutionRealm

fn clone(&self) -> ExecutionRealm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ExecutionRealm

impl Debug for ExecutionRealm

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExecutionRealm

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

Deserialize this value from the given Serde deserializer.

impl Eq for ExecutionRealm

impl Hash for ExecutionRealm

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,

impl Ord for ExecutionRealm

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ExecutionRealm

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