In Immutables: Fast and Functional Data Structures

Build a Priority Queue from x and priorities

Description

Constructs a queue by pairing each element of x with the corresponding value in priorities.

Usage

as_priority_queue(x, priorities)

Arguments

x	Elements to enqueue.
priorities	Priorities with the same length as x.

Details

x is interpreted element-wise (via list coercion). Names on x are preserved as queue element names.

All priorities must be non-missing and mutually comparable.

Value

A priority_queue.

Examples

x <- as_priority_queue(letters[1:4], priorities = c(3, 1, 2, 1))
x
peek_min(x)
peek_max(x)

# Names are preserved
n <- as_priority_queue(setNames(as.list(1:3), c("a", "b", "c")), priorities = c(2, 1, 3))
n[["b"]]
