Enum platforms::target::Env [−][src]
pub enum Env { GNU, MSVC, Musl, uClibc, Unknown, }
target_env
: Target enviroment that disambiguates the target platform by ABI / libc.
This value is closely related to the fourth element of the platform target triple,
though it is not identical. For example, embedded ABIs such as gnueabihf
will simply
define target_env
as "gnu"
(i.e. target::Env::GNU
)
Variants
GNU
gnu
: The GNU C Library (glibc)
MSVC
msvc
: Microsoft Visual C(++)
Musl
musl
: Clean, efficient, standards-conformant libc implementation.
uClibc
uclibc
: C library for developing embedded Linux systems
Unknown
Unknown target environment
