pub struct BuildOutput {
    pub library_paths: Vec<PathBuf>,
    pub library_links: Vec<String>,
    pub linker_args: Vec<(LinkType, String)>,
    pub cfgs: Vec<String>,

}

Contains the parsed output of a custom build script.

Fields

library_paths: Vec<PathBuf>

Paths to pass to rustc with the -L flag.

library_links: Vec<String>

Names and link kinds of libraries, suitable for the -l flag.

linker_args: Vec<(LinkType, String)>

Linker arguments suitable to be passed to -C link-arg=<args>

cfgs: Vec<String>

Various --cfg flags to pass to the compiler.

env: Vec<(String, String)>

Additional environment variables to run the compiler with.

metadata: Vec<(String, String)>

Metadata to pass to the immediate dependencies.

rerun_if_changed: Vec<PathBuf>

Paths to trigger a rerun of this build script. May be absolute or relative paths (relative to package root).

rerun_if_env_changed: Vec<String>

Environment variables which, when changed, will cause a rebuild.

warnings: Vec<String>

Warnings generated by this build.

These are only displayed if this is a “local” package, -vv is used, or there is a build error for any target in this package.
