Struct Context 

pub struct Context { /* private fields */ }

A struct which keeps track of the context leading up to some expression, e.g. its depth, what variables are accessible, and whether the context has a constant function.

Implementations

impl Context

pub fn len(&self) -> usize

The length of the context thus far.

pub fn n_vars(&self) -> usize

The number of variables in the current Context

pub fn is_constant(&self) -> bool

Does the context have any constant functions preceding it?

pub fn current_variable_types(&self) -> impl Iterator<Item = &LambdaType>

What are the current possible variable types

pub fn applications<'a, 'b: 'a>( &'a self, lambda_type: &'b LambdaType, ) -> impl Iterator<Item = (LambdaType, LambdaType)> + 'a

What possible applications can be created at this point?

pub fn variables<'src, T: LambdaLanguageOfThought>( &self, lambda_type: &LambdaType, ) -> impl Iterator<Item = LambdaExpr<'src, T>>

What are the current variables?

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Ord for Context

fn cmp(&self, other: &Self) -> 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 Context

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

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