Variants§
Add
The +
operator (addition)
Sub
The -
operator (subtraction)
Mul
The *
operator (multiplication)
Div
The /
operator (division)
Division by zero is UB, because the compiler should have inserted checks prior to this.
Rem
The %
operator (modulus)
Using zero as the modulus (second operand) is UB, because the compiler should have inserted checks prior to this.
BitXor
The ^
operator (bitwise xor)
BitAnd
The &
operator (bitwise and)
BitOr
The |
operator (bitwise or)
Shl
The <<
operator (shift left)
The offset is truncated to the size of the first operand before shifting.
Shr
The >>
operator (shift right)
The offset is truncated to the size of the first operand before shifting.
Eq
The ==
operator (equality)
Lt
The <
operator (less than)
Le
The <=
operator (less than or equal to)
Ne
The !=
operator (not equal to)
Ge
The >=
operator (greater than or equal to)
Gt
The >
operator (greater than)
Offset
The ptr.offset
operator

source§fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool
fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool
true
if self
has any late-bound regions that are either
bound by binder
or bound by some binder outside of binder
.
If binder
is ty::INNERMOST
, this indicates whether
there are any late-bound regions that appear free. Read moresource§fn has_vars_bound_above(&self, binder: DebruijnIndex) -> bool
fn has_vars_bound_above(&self, binder: DebruijnIndex) -> bool

if this type has any regions that escape binder
(and
hence are not bound by it). Read moresource§fn has_escaping_bound_vars(&self) -> bool
fn has_escaping_bound_vars(&self) -> bool
true
if this type has regions that are not a part of the type.
For example, for<'a> fn(&'a i32)
return false
, while fn(&'a i32)
would return true
. The latter can occur when traversing through the
former. Read morefn has_type_flags(&self, flags: TypeFlags) -> bool
