Struct BindingIndex 

pub struct BindingIndex {
    server: String,
    bound: HashMap<PolicyId, Vec<Coverage>>,
    names: HashMap<PolicyId, String>,
}

Whom each policy in a tree is bound to, by the tree’s own id for it.

A policy with no entry is unbound — compiled in, or supplied at startup — and applies to every account. A policy with an entry applies within a Boundary one of its coverages reaches, and one with an empty entry applies to nobody.

Fields

server: String

bound: HashMap<PolicyId, Vec<Coverage>>

names: HashMap<PolicyId, String>

Each policy’s id in the build: {key}/{statement}/{action} for a record, the name for a built-in.

Implementations

impl BindingIndex

pub fn of( server: &str, bindings: &BTreeMap<String, PolicyBinding>, ids: &BTreeMap<String, Vec<String>>, registered: &HashMap<String, PolicyId>, ) -> (Self, Vec<String>)

The index over one build’s records: every declaration registered holds a tree position for, carrying the reach of every binding that names the record it was declared from.

ids is the declaration ids each policy record was declared under — crate::set::Read::ids. Also returns the record keys no binding names, in key order: compiled, and applied to nobody.

pub fn name_of(&self, policy: PolicyId) -> Option<&str>

The id policy was registered under, for a refusal that names it.

pub fn applies(&self, policy: PolicyId, boundary: &Boundary) -> bool

Whether policy reaches the account judged within boundary.

pub fn len(&self) -> usize

How many policies carry a binding.

pub fn is_empty(&self) -> bool

Whether no policy carries a binding.
