Struct Resolver 

pub struct Resolver<'a> { /* private fields */ }

Resolves references, fetching each distinct path once.

Implementations

impl<'a> Resolver<'a>

pub fn new(source: &'a dyn SecretSource) -> Resolver<'a>

pub fn fetches(&self) -> usize

How many distinct paths have been fetched.

pub async fn value(&mut self, key: &str, value: &str) -> Result<Option<String>>

Resolve one value, or None if it was not a reference.

pub async fn pairs( &mut self, pairs: &mut BTreeMap<String, String>, ) -> Result<usize>

Resolve every reference in a flat map, in place, and say how many.

This is the shape a parsed .env comes in, and the shape anything else keyed by name can be put into.

pub async fn config(&mut self, config: &Config, roots: &[&str]) -> Result<usize>

Resolve every reference under each of these configuration paths.

The roots have to be named because Config offers no way to enumerate its top level, and a resolver that guessed at namespaces would be the runtime magic this framework does without. Each root is a dotted path and its whole subtree is searched, so "database" covers database.connections.pgsql.password.
