print=supported-crate-types
The tracking issue for this feature is: #138640.
This option of the --print flag produces a list of crate types (delimited by newlines) supported for the given target.
The crate type strings correspond to the values accepted by the --crate-type flag.
Intended to be used like this:
rustc --print=supported-crate-types -Zunstable-options --target=x86_64-unknown-linux-gnu
Example output for x86_64-unknown-linux-gnu:
bin
cdylib
dylib
lib
proc-macro
rlib
staticlib
