|
|
|

|
|
|
38
|
|
|
|
|
|
|
This distribution provides Rust so that it can be used by other |
39
|
|
|
|
|
|
|
Perl distributions that are on CPAN. It does this by first trying to |
40
|
|
|
|
|
|
|
detect an existing install of Rust on your system. If found it |
41
|
|
|
|
|
|
|
will use that. If it cannot be found, the source code will be downloaded |
42
|
|
|
|
|
|
|
from the internet and it will be installed in a private share location |
43
|
|
|
|
|
|
|
for the use of other modules. |

Returns the value for the environment variable C. This is valid only |
50
|
|
|
|
|
|
|
if L returns true. |
51
|
|
|
|
|
|
|
|
52
|
|
|
|
|
|
|
Without this value, certain Rust configurations that use |
53
|
|
|
|
|
|
|
L|https://rust-lang.github.io/rustup/> will not work as their |
54
|
|
|
|
|
|
|
binaries (e.g., C, C, etc.) are shims that point to the toolchain |
55
|
|
|
|
|
|
|
managed by C. |
