Methods

impl DepGraphBuilder

fn new() -> DepGraphBuilder

Create a DepGraphBuilder with no rules.

fn add_rule<F, P1, P2>(
    self,
    filename: P1,
    dependencies: &[P2],
    build_fn: F
) -> DepGraphBuilder where
    F: Fn(&Path, &[&Path]) -> Result<(), String> + 'static,
    P1: AsRef<Path>,
    P2: AsRef<Path>, 

Add a new rule (a file with its dependent files and build instructions).

These can be added in any order, and can be chained.

fn add_dep_to_all<P>(self, dep: P) -> DepGraphBuilder where
    P: AsRef<Path>, 

Add a dependency to all previously added files. Will only affect previously added files, not those added in the future.

This can be used to make all rules depend on build.rs, for example.

fn build(self) -> DepResult<DepGraph>

Build the make graph and check for errors like cyclic dependencies and duplicate files.
