Struct cc::Tool [−][src]
pub struct Tool { /* fields omitted */ }
Expand description
Configuration used to represent an invocation of a C compiler.
This can be used to figure out what compiler is in use, what the arguments
to it are, and what the environment variables look like for the compiler.
This can be used to further configure other build systems (e.g. forward
along CC and/or CFLAGS) or the to_command
method can be used to run the
compiler itself.
Implementations
Converts this compiler into a Command
that’s ready to be run.
This is useful for when the compiler needs to be executed and the command returned will already have the initial arguments and environment variables configured.
Returns the path for this compiler.
Note that this may not be a path to a file on the filesystem, e.g. “cc”, but rather something which will be resolved when a process is spawned.
Returns the default set of arguments to the compiler needed to produce executables for the target this compiler generates.
Returns the set of environment variables needed for this compiler to operate.
This is typically only used for MSVC compilers currently.
Returns the compiler command in format of CC environment variable. Or empty string if CC env was not present
This is typically used by configure script
Returns the compiler flags in format of CFLAGS environment variable. Important here - this will not be CFLAGS from env, its internal gcc’s flags to use as CFLAGS This is typically used by configure script
Whether the tool is GNU Compiler Collection-like.
Whether the tool is Clang-like.
Whether the tool is MSVC-like.
