Struct Config 

pub struct Config { /* private fields */ }

A merged configuration, and where each of its values came from.

Implementations

impl Config

pub fn root(&self) -> Option<&Node>

The merged tree, or None when nothing was loaded.

pub fn sources(&self) -> &[String]

Every file that contributed, in the order it was read.

pub fn get(&self, path: &str) -> Option<&Node>

The node at a dotted path.

pub fn get_str(&self, path: &str) -> Option<&str>

The scalar at a dotted path.

pub fn origin_of(&self, path: &str) -> Option<&Origin>

Where the value at a dotted path came from.

This is the question a layered configuration exists to answer.

pub fn push(&mut self, node: Node, source: String) -> Result<(), ConfigError>

Merges one more source in, after everything already there. A refused layer leaves both the effective tree and source list unchanged.

Errors

Whatever Node::merge reports.

pub fn push_each( &mut self, nodes: Vec<Node>, source: String, ) -> Result<(), ConfigError>

Merges several trees in, one after another, as one source. Each tree’s +name appends to what the ones before it left, which one pre-merged tree could not express. All or nothing, like Self::push.

Errors

Whatever Node::merge reports.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.
