interval

(T

type

:

integer, from T, through option T, step T)

:

is

[Module base]

An interval `from..through` that includes `from`, `from+step`, `from+step+step`,
etc. up to and including `through`.

In case step is positive (negative), the first value larger (smaller) than
through will not be included.

In case `step.sign = (from ⋄ through).sign`, this `Set` is empty, e.g.,
`interval 1 2 -1` and `interval 2 1 1` are both empty.

Type Parameters

T

:

[Module base]

Fields

from

T

[Module base]

the first element of this Set when used as a Sequence

through

[Module base]

upper/lower bound for elements in this Set

in case this is nil, there is no bound except for the
range of legal values for T.

step

T

[Module base]

the distance between to elements

Functions

group_hashable_by

(K

type

:

property.hashable, f Unary K Sequence.T)

=>

container.Map K (Sequence Sequence.T)

[Inherited from Sequence]

[Contains abstract features]

group the elements of this sequence by a key of type K

f determines the key of an element
