Struct chalk_ir::Environment [−][src]
pub struct Environment<I: Interner> { pub clauses: ProgramClauses<I>, }
Expand description
The set of assumptions we’ve made so far, and the current number of universal (forall) quantifiers we’re within.
Fields
clauses: ProgramClauses<I>
The clauses in the environment.
Implementations
pub fn add_clauses<II>(&self, interner: &I, clauses: II) -> Self where
II: IntoIterator<Item = ProgramClause<I>>,
[src]
pub fn add_clauses<II>(&self, interner: &I, clauses: II) -> Self where
II: IntoIterator<Item = ProgramClause<I>>,
[src]Adds (an iterator of) clauses to the environment.
True if any of the clauses in the environment have a consequence of Compatible
.
Panics if the conditions or constraints of that clause are not empty.
Trait Implementations
type Result = Environment<I>
type Result = Environment<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 !=
.

[src]Apply the given visitor visitor
to self
; binders
is the
number of binders that are in scope when beginning the
visitor. Typically binders
