Trait Implementations

impl<I: Clone + Interner> Clone for FnSubst

source

fn clone(&self) -> FnSubst

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl<I: Interner> Debug for FnSubst

source

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

Formats the value using the given formatter. Read more

source

impl<I: Interner> Fold for FnSubst

type Result = FnSubst

The type of value that will be produced once folding is done. Typically this is Self, unless Self contains borrowed values, in which case owned values are produced (for example, one can fold over a &T value where T: Fold, in which case you get back a T, not a &T). Read more

source

fn fold_with<E>(
 self,
 folder: &mut dyn Folder<I, Error = E>,
 outer_binder: DebruijnIndex
) -> Result<Self::Result, E>

Apply the given folder folder to self; binders is the number of binders that are in scope when beginning the folder. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs. Read more

source

impl<I: Interner> HasInterner for FnSubst

type Interner = I

The interner associated with the type.

source

impl<I: Hash + Interner> Hash for FnSubst

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher. Read more

source

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

This method tests for !=.

source

impl<I: Interner> Visit for FnSubst

source

fn visit_with(
 &self,
 visitor: &mut dyn Visitor<I, BreakTy = B>,
 outer_binder: DebruijnIndex
) -> ControlFlow

Apply the given visitor visitor to self; binders is the number of binders that are in scope when beginning the visitor. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs. Read more

fn zip_with<Z: Zipper>(
 zipper: &mut Z,
 variance: Variance,
 a: &Self,
 b: &Self
) -> Fallible<()>

Uses the zipper to walk through two values, ensuring that they match.
