pub struct ProgramClauseData<I: Interner>(pub Binders<ProgramClauseImplication<I>>);Expand description
Contains the data for a program clause.
Tuple Fields
0: Binders<ProgramClauseImplication<I>>Implementations

Intern the program clause data.
Trait Implementations
fn could_match(
&self,
interner: I,
db: &dyn UnificationDatabase<I>,
other: &DomainGoal<I>
) -> bool
fn could_match(
&self,
interner: I,
db: &dyn UnificationDatabase<I>,
other: &DomainGoal<I>
) -> bool
Checks whether self and other could possibly match.
type Result = ProgramClauseData<I>
type Result = ProgramClauseData<I>
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
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
type Interner = I
type Interner = I
The interner associated with the type.
This method tests for self and other values to be equal, and is used
by ==. Read more
This method tests for !=.
fn super_fold_with<E>(
self,
folder: &mut dyn Folder<I, Error = E>,
outer_binder: DebruijnIndex
) -> Result<Self::Result, E>
fn super_fold_with<E>(
self,
folder: &mut dyn Folder<I, Error = E>,
outer_binder: DebruijnIndex
) -> Result<Self::Result, E>
Recursively folds the value.

Shifts this term in one level of binders.
Shifts a term valid at outer_binder so that it is
valid at the innermost binder. See DebruijnIndex::shifted_in_from
for a detailed explanation. Read more
