rust - Specific profiles for workspace members -


is possible specify specific profiles members of workspace? if write profile member cargo.toml get:

warning: profiles non root package ignored, specify profiles @ workspace root:

i tried put specific profile workspace root's cargo.toml:

[profile.release] opt-level = 3  [profile.release.hal] # optimizer kills assembly code opt-level = 1

however, seems ignored too, applied options in the verbose output show:

running `rustc --crate-name hal src/hal/lib.rs --crate-type lib -c opt-level=3 --emit=dep-info,link [...]

is there other way beside avoiding workspaces @ all?

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
