Trait Implementations

impl TraverseNeutral for Closure

fn try_map_neutral<R>(
    self,
    f: &mut impl FnMut(Neutral) -> Result<Val, R>
) -> Result<Self, R>

Map all Neutral values in this expression.

fn try_fold_neutral<E, R>(
    self,
    init: R,
    f: impl Fn(R, Neutral) -> Result<R, E> + Copy
) -> Result<R, E>

Fold all Neutral values in this expression.

fn fold_neutral<R>(self, init: R, f: impl Fn(R, Neutral) -> R + Copy) -> R

Traverse all Neutral values the AST in a stateful manner.

fn map_neutral(self, f: &mut impl FnMut(Neutral) -> Val) -> Self

Traverse through the AST and change all Neutral values.

impl RedEx<Closure> for Closure

fn reduce_with_dbi(self, arg: Val, dbi: DBI) -> Self

This is primarily a private implementation-related API. Use at your own risk.

fn reduce_with_dbi_borrow(self, arg: &Val, dbi: DBI) -> Self

When the argument is not likely to be used, prefer this over reduce_with_dbi.

impl Eq for Closure

fn assert_receiver_is_total_eq(&self)

impl Default for Closure

fn default() -> Self

Returns the "default value" for a type.

impl Clone for Closure

fn clone(&self) -> Closure

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Closure> for Closure

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Debug for Closure

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

Formats the value using the given formatter.

impl Display for Closure

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

Formats the value using the given formatter.

impl LiftEx for Closure

fn lift(self, levels: LevelType) -> Self

Lift the level of self.

fn calc_level(&self) -> LevelCalcState

Internal API, for code sharing only.

fn level(&self) -> Level

Calculate the level of self, like a normal value will have level 0, a type expression will have level 1 (or higher).
