Language Feature Scripts

There are also a number of examples scripts that showcase Rhai's features, all in the scripts directory:

Script	Description
array.rhai	[arrays] example
assignment.rhai	[variable] declarations
comments.rhai	just regular [comments]
doc-comments.rhai	[doc-comments] example
for1.rhai	[for] loops
for2.rhai	[for] loops with [array] iterations
for3.rhai	[for] loops with [closures]
function_decl1.rhai	a [function] without parameters
function_decl2.rhai	a [function] with two parameters
function_decl3.rhai	a [function] with many parameters
function_decl4.rhai	a [function] acting as a method
function_decl5.rhai	multiple [functions] as methods for different data types
if1.rhai	[if] example
if2.rhai	[if]-expression example
loop.rhai	count-down [loop] in Rhai, emulating a [do] ... while loop

Benchmark Scripts

The following scripts are for benchmarking the speed of Rhai:

Scripts	Description
speed_test.rhai	a simple application to measure the speed of Rhai's interpreter (1 million iterations)
primes.rhai	use Sieve of Eratosthenes to find all primes smaller than a limit
fibonacci.rhai	calculate the n-th Fibonacci number using a really dumb algorithm
mat_mul.rhai	matrix multiplication test to measure the speed of multi-dimensional array access

Run Example Scripts

The rhai-run utility can be used to run Rhai scripts:

cargo run --bin rhai-run scripts/any_script.rhai
