Struct gcc::Tool

pub struct Tool {
    // some fields omitted
}

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.

Methods

impl Tool

fn to_command(&self) -> Command

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.

fn path(&self) -> &Path

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.

fn args(&self) -> &[OsString]

Returns the default set of arguments to the compiler needed to produce executables for the target this compiler generates.

fn env(&self) -> &[(OsString, OsString)]

Returns the set of environment variables needed for this compiler to operate.

This is typically only used for MSVC compilers currently.
