Undocumented

Returns

f(x)

=~(x:Any, t:Type, _mc:MatchContext) Source: stdlib.ngs:945

Check whether x is of type t

Returns

x is t

=~(x:Any, l:Lit, _mc:MatchContext) Source: stdlib.ngs:948

Check whether x is the literal value l (using ==)

=~(x:Eachable1, r:Repeat, mc:MatchContext) Source: stdlib.ngs:968

Returns

Bool

=~(x:Any, n:Not, mc:MatchContext) Source: stdlib.ngs:997

Negate the match

Returns

Undocumented

=~(x:Any, a:AnyOf, mc:MatchContext) Source: stdlib.ngs:1579

Check whether one of the patterns (elements of AnyOf) matches

Example

{"k1": "v1", "k2": "v2", "k3": "v3"}.filterk(AnyOf("k1", "k3"))  # {"k1": "v1", "k3": "v3"}

=~(x:Any, a:AllOf, mc:MatchContext) Source: stdlib.ngs:1603

Checks whether one of the patterns (elements of AllOf) matches

Example

{"k1": "v1", "k2": "v2", "kk3": "vv3"}.filterk(AllOf(/^k/, {len(A) <= 2})) == %{k1 v1 k2 v2}

=~(x:Any, nr:NumRange, _mc:MatchContext) Source: stdlib.ngs:2249

Example

1 =~ 0..5  # true

=~(x:Any, p:Present, mc:MatchContext) Source: stdlib.ngs:4041

Checks element presence.

Returns

Bool

Example

[1,2,3] =~ Present(3)  # MatchSuccess

=~(x:Any, a:Absent, mc:MatchContext) Source: stdlib.ngs:4059
