PartialEq
implementation signature
Equality definition.
It must satisfy all of the following conditions:
A
implements PartialEq
and module B
implements PartialEq
, and A.PartialEq.t
is equal to B.PartialEq.rhs
and B.PartialEq.t
is equal to A.PartialEq.rhs
, then eq (module A) a b
implies eq (module B) b a
A
, A'
, B
and C
all implement PartialEq
, and A.PartialEq.rhs
is equal to B.PartialEq.t
, and B.PartialEq.rhs
is equal to C.PartialEq.t
, and A'.Partial.rhs
is equal to c.PartialEq.t
, then eq (module A) a b
and eq (module B) b c
implies eq (module A') a c
Inequality definition. Must ensure that it is consistent with eq
: ne x y
if true if and only if not (eq x y)
In most cases, Traits.PartialEq.Make
should be used to derive this function automatically. However, there may be cases where it may be more desirable (efficient, clear) to implement it manually.
