Does Rust have a way to apply a function/method to each element in an array or vector? -


does rust language have way apply function each element in array/vector. know in python there map() function performs task. in r there lapply(), tapply(), , apply() functions this. wondering if there established way vectorize function in rust?

there's few subtleties here:

we have map, works on iterators. can:

some_vec.iter().map(|x| { })

however, iterators lazy, won't anything. can tack .collect() onto end make new vector new elements, if that's want.

the standard way without allocating use loop:

for in &vec {

if want functional style, can use forall method in itertools crate.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
