Module `CCEqual`Source

Equality Combinators

since 1.2

Sourcetype 'a t = 'a -> 'a -> bool

Equality function. Must be transitive, symmetric, and reflexive.

Sourceval poly : 'a t

Standard polymorphic equality.

Sourceval physical : 'a t

Standard physical equality.

since 2.0

Sourceval int : int t

Sourceval string : string t

Sourceval bool : bool t

Sourceval float : float t

Sourceval unit : unit t

Sourceval list : 'a t -> 'a list t

Sourceval array : 'a t -> 'a array t

Sourceval option : 'a t -> 'a option t

Sourceval pair : 'a t -> 'b t -> ('a * 'b) t

Sourceval triple : 'a t -> 'b t -> 'c t -> ('a * 'b * 'c) t

Sourceval map : ('a -> 'b) -> 'b t -> 'a t

map f eq is the equality function that, given objects x and y, projects x and y using f (e.g. using a record field) and then compares those projections with eq. Example: map fst int compares values of type (int * 'a) by their first component.

Sourceval always_eq : _ t

Always returns true. All values are equal.

since 3.0

Sourceval never_eq : _ t

Always returns false. No values are, so this is not even reflexive (i.e. x=x is false). Be careful!

since 3.0

Sourcemodule Infix : sig ... end

include module type of Infix

Sourceval (>|=) : 'b t -> ('a -> 'b) -> 'a t

Infix equivalent of map.
