Struct ConfigLayer 

pub struct ConfigLayer {
    pub source: ConfigSource,
    /* private fields */
}

A deterministic map of configuration values paired with source metadata.

Fields

source: ConfigSource

Source metadata for this layer.

Implementations

impl ConfigLayer

pub const fn new(source: ConfigSource) -> ConfigLayer

Creates an empty layer for a source.

pub const fn from_values( source: ConfigSource, values: BTreeMap<ConfigPath, ConfigValue>, ) -> ConfigLayer

Creates a layer from source metadata and values.

pub const fn source(&self) -> &ConfigSource

Returns the layer source.

pub const fn values(&self) -> &BTreeMap<ConfigPath, ConfigValue>

Returns the deterministic value map.

pub fn len(&self) -> usize

Returns the number of values in the layer.

pub fn is_empty(&self) -> bool

Returns true when the layer has no values.

pub fn insert( &mut self, path: ConfigPath, value: ConfigValue, ) -> Option<ConfigValue>

Inserts a path value into the layer.

pub fn get(&self, path: &ConfigPath) -> Option<&ConfigValue>

Returns a value for a path.

pub fn iter(&self) -> impl Iterator<Item = (&ConfigPath, &ConfigValue)>

Iterates over values in deterministic path order.

Trait Implementations

impl Clone for ConfigLayer

fn clone(&self) -> ConfigLayer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigLayer

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

Formats the value using the given formatter.

impl PartialEq for ConfigLayer

fn eq(&self, other: &ConfigLayer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
