rust_eval | R Documentation |
Compile and evaluate one or more Rust expressions. If the last
expression in the Rust code returns a value (i.e., does not end with
;
), then this value is returned to R. The value returned does not need
to be of type Robj
, as long as it can be cast into this type with
.into()
. This conversion is done automatically, so you don't have to
worry about it in your code.
rust_eval(code, env = parent.frame(), ...)

Input rust code. |
env |
The R environment in which the Rust code will be evaluated. |

The return value generated by the Rust code.
## Not run:
# Rust code without return value, called only for its side effects
rust_eval(
code = 'rprintln!("hello from Rust!");'
)
# Rust code with return value
rust_eval(
code = "
let x = 5;
let y = 7;
let z = x * y;
z // return to R; rust_eval() takes care of type conversion code
"
)
