error[E0425]: cannot find value `target` in this scope
--> $DIR/trivial-const-arg-macro-res-error.rs:5:9
|
LL | target
| ^^^^^^ not found in this scope
...
LL | let val: [str; len!()] = [];
| ------ in this macro invocation
|
= note: this error originates in the macro `len` (in Nightly builds, run with -Z macro-backtrace for more info)
error[E0277]: the size for values of type `str` cannot be known at compilation time
--> $DIR/trivial-const-arg-macro-res-error.rs:11:14
|
LL | let val: [str; len!()] = [];
| ^^^^^^^^^^^^^ doesn't have a size known at compile-time
|
= help: the trait `Sized` is not implemented for `str`
= note: slice and array elements must have `Sized` type
error: aborting due to 2 previous errors
Some errors have detailed explanations: E0277, E0425.
