PathStrategy

scion_stack::path

Struct PathStrategy 

Source 
pub struct PathStrategy {
    pub policies: Vec<Arc<dyn PathPolicy>>,
    /* private fields */
}
Expand description

PathStrategy combines multiple path operations into a single strategy.

Fields§

§policies: Vec<Arc<dyn PathPolicy>>

The path policies to apply.

Implementations§

Source§

impl PathStrategy

Source

pub fn add_policy(&mut self, policy: impl PathPolicy)

Appends a path policy to the list of policies.

Source

pub fn predicate(&self, path: &ScionPath) -> bool

Returns true if the given path is accepted by all policies.

If no policies are added, all paths are accepted.

Source

pub fn filter_inplace(&self, paths: &mut Vec<ScionPath>)

Filters the given paths based on all policies, removing paths that are not accepted.
