Trait Implementations

impl Clone for Ext

fn clone(&self) -> Ext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ext

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

Formats the value using the given formatter.

impl Eq for Ext

impl From<Ext> for Term

fn from(ext: Ext) -> Self

Converts to this type from the input type.

impl Ord for Ext

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Ext

fn partial_cmp(&self, other: &Ext) -> 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 StructuralPartialEq for Ext

impl TryFrom<&Ext> for Value

type Error = ExtError

The type returned in the event of a conversion error.

fn try_from(ext: &Ext) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&RestrictedExpr> for Ext

Rust SymCC and Rust Cedar use different representations of extension values (whereas the Lean model uses the same), so we need these utility functions to convert between them.

type Error = ExtError

The type returned in the event of a conversion error.

fn try_from(rexp: &RestrictedExpr) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&Value> for Ext

type Error = ExtError

The type returned in the event of a conversion error.

fn try_from(v: &Value) -> Result<Self, Self::Error>

Performs the conversion.
