pass_multiple_integers: Multiplies an integer vector by 10 in Rust
In ericwburden/rustbind: Minimal Example of Calling Rust from R

Description Usage Arguments Details Value Examples

Demonstrates passing an integer vector back and forth between R and Rust, multiplies each element by 10 in Rust to prove it works.

1	pass_multiple_integers(n)

`n`	An integer vector to treat as an extendr_api::Int in Rust

The vector passed to this function must be an integer (from as.integer(n)) or an NA_integer_. The Rust function signature is fn pass_multiple_integers(n: Int) -> Int. In the current version of extendr-api (0.2.0), NA's are implicitly converted to 0's, so if you need NA handling you'll need to take care of that yourself for now.

pass_multiple_integers(as.integer(c(5, 7, 9)))  # c(50, 70, 90)
pass_multiple_integers(as.integer(30))          # 300
pass_multiple_integers(NA_integer_)             # 0
