as.list.rpqueue {rstackdeque}

Convert an rpqueue to a list

Description

Converts an rpqueue to a list, where the front of the queue becomes the first element of the list, the second-from-front the second, and so on.

Usage

## S3 method for class 'rpqueue'
as.list(x, ...)

Arguments

x

rpqueue to convert.

...

additional arguments passed to as.list after initial conversion to list.

Details

Runs in O(N) time in the size of the rpqueue, but the generated list is pre-allocated for efficiency.

Value

a list containing the elements of the rpqueue in front-to-back order.
