Struct ConfigSources 

pub struct ConfigSources { /* private fields */ }

Map of dotted field name → source. Stored alongside the live Config so callers can ask config.source_of("endpoint").

Implementations

impl ConfigSources

pub fn new() -> Self

pub fn set(&mut self, key: impl Into<String>, source: ConfigSource)

Record (or replace) the source for a dotted field name.

pub fn get(&self, key: &str) -> Option<&ConfigSource>

Look up the recorded source for a dotted field name.

pub fn iter(&self) -> impl Iterator<Item = (&String, &ConfigSource)>

Iterator over (key, source) pairs in insertion-stable sorted order.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
