Trait config::Source

pub trait Source: Debug {
    // Required methods
    fn clone_into_box(&self) -> Box<dyn Source + Send + Sync>;
    fn collect(&self) -> Result<Map<String, Value>, ConfigError>;

    // Provided method
    fn collect_to(&self, cache: &mut Value) -> Result<(), ConfigError> { ... }
}

Describes a generic source of configuration properties.

Required Methods

fn clone_into_box(&self) -> Box<dyn Source + Send + Sync>

fn collect(&self) -> Result<Map<String, Value>, ConfigError>

Collect all configuration properties available from this source and return a Map.

Provided Methods

fn collect_to(&self, cache: &mut Value) -> Result<(), ConfigError>

Collects all configuration properties to a provided cache.

Trait Implementations
