Module File_path.RelativeSource

Relative paths are a subtype of Path.t and therefore also of string.

type comparator_witness = Types.Relative.comparator_witness
include Types.Type with type t := t and type comparator_witness := comparator_witness
include Ppx_compare_lib.Equal.S with type t := t
include Ppx_compare_lib.Comparable.S with type t := t
include Ppx_hash_lib.Hashable.S with type t := t
Sourceval t_sexp_grammar : t Sexplib0.Sexp_grammar.t
include Core.Comparator.S with type t := t with type comparator_witness := comparator_witness
Sourcemodule Expert : sig ... end

Path types have straightforward to_string and sexp_of_t behavior. of_string and t_of_sexp raise on invalid input (e.g. containing null characters), and guarantee canonical output (e.g. no redundant slashes).

to_string is the identity function. of_string returns its input when the input is a valid string in canonical form.

include Core.Identifiable.S with type t := t and type comparator_witness := comparator_witness
include Bin_prot.Binable.S with type t := t
include Bin_prot.Binable.S_only_functions with type t := t
Sourceval bin_size_t : t Bin_prot.Size.sizer
Sourceval bin_write_t : t Bin_prot.Write.writer
Sourceval bin_read_t : t Bin_prot.Read.reader
Sourceval __bin_read_t__ : (int -> t) Bin_prot.Read.reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.

val (>=) : t -> t -> bool
val (<=) : t -> t -> bool
val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).
