Trait TopologyOps 

pub trait TopologyOps {
    // Required method
    fn sort(
        &self,
        names: &[&str],
        requires: &[&[&str]],
    ) -> Result<Vec<usize>, ConfigError>;
}

Topological dependency resolver for feature load ordering.

Implemented by crate::Topology.

Required Methods

fn sort( &self, names: &[&str], requires: &[&[&str]], ) -> Result<Vec<usize>, ConfigError>

Return a topological ordering of the provided names.

names is the list of feature names; requires[i] is the slice of dependencies for names[i].

Errors

Returns ConfigError::Validation listing all nodes involved in a detected cycle.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
