A RaceSeq is the intermediate object used when race is invoked on a Seq. In general, it's not intended for direct consumption by the developer.

Methods §

method iterator §

Raku highlighting

method iterator(RaceSeq:D: --> Iterator:D)

Code

Returns the underlying iterator.

Raku highlighting

method grep(RaceSeq:D: $matcher, *%options)

Code

Applies grep to the RaceSeq similarly to how it would do it on a Seq.

Raku highlighting

my @raced = (^10000).map(*²).race;
@raced.grep( * %% 3 ).say;
# OUTPUT: «(0 9 36 81 144 ...)␤»

Code

When you use race on a Seq, this is the method that is actually called.

Raku highlighting

method map(RaceSeq:D: $matcher, *%options)

Code

Uses maps on the RaceSeq, generally created by application of .race to a preexisting Seq.

Raku highlighting

method invert(RaceSeq:D:)

Code

Inverts the RaceSeq created from a Seq by .race.

Raku highlighting

method race(RaceSeq:D:)

Code

Returns the object.

Raku highlighting

method hyper(RaceSeq:D:)

Code

Creates a HyperSeq object out of the current one.

Raku highlighting

multi method serial(RaceSeq:D:)

Code

Converts the object to a Seq and returns it.

Raku highlighting

method is-lazy(--> False )

Code

Returns False.

Raku highlighting

method sink(--> Nil)

Code
