Struct ConfigMap 

pub struct ConfigMap { /* private fields */ }

Internal data model for configuration values.

Supports two access patterns:

• Flat — top-level KEY = value (.env, root of JSON/TOML/YAML)
• Sectioned — [section] key = value (INI, nested TOML/JSON/YAML)

Implementations

impl ConfigMap

pub fn new() -> Self

Create an empty map.

pub fn insert_flat(&mut self, key: String, value: String)

Insert a flat (top-level) key/value pair.

pub fn insert_sectioned(&mut self, section: String, key: String, value: String)

Insert a sectioned key/value pair.

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

Look up a flat key.

pub fn get_in_section(&self, section: &str, key: &str) -> Option<&str>

Look up key inside section.

pub fn get_section(&self, section: &str) -> Option<&IndexMap<String, String>>

Return all key/value pairs for section.

pub fn has_section(&self, section: &str) -> bool

True if section exists.

pub fn flat_iter(&self) -> impl Iterator<Item = (&str, &str)>

All flat key/value pairs in insertion order.

pub fn sections( &self, ) -> impl Iterator<Item = (&str, &IndexMap<String, String>)>

All sections, each yielding its key/value pairs.

pub fn len(&self) -> usize

Total number of top-level keys (flat + section names).

pub fn is_empty(&self) -> bool

True if there are no flat keys and no sections.

pub fn contains_key(&self, key: &str) -> bool

True if the flat map contains key or any section contains key.

Trait Implementations

impl Default for ConfigMap

fn default() -> ConfigMap

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ConfigMap

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ConfigMap

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
