我如何使“ rustc”的注释静音，以免链接到哪些本地工件？

Question

I've got a project where Rust source files are being automatically generated and compiled into static libraries. I'd like the output of rustc to be streamed to stdout and stderr as usual, but I wish that the following note wasn't always emitted:

note: link against the following native artifacts when linking against this static library

note: the order and any duplication can be significant on some platforms, and so may need to be preserved

note: library: System

note: library: resolv

note: library: c

note: library: m

Is there any way to silence this without silencing too much else? The note was useful to me when I was figuring out how to link things automatically, but it won't be useful to my users who never actually see the linking process.

In Rust 1.21 and earlier, there is no way to turn off the output.

In Rust 1.22, the --print=native-static-libs option was added. When it is not present, it outputs:

note: This list will not be printed by default. Please add --print native-static-libs if you need this information.

Adding the option will silence the warning.

To silence this information without silencing anything else, upgrade to Rust 1.23 once it's released.
