Trait ConfigTrait 

pub trait ConfigTrait: Sized {
    // Required methods
    fn load(sources: &[ConfigSource]) -> Result<Self, ConfigError>;
    fn field_meta() -> &'static [ConfigFieldMeta];
}

Trait implemented by #[derive(Config)] structs.

Provides config loading from multiple sources with a defined precedence order, and field introspection for tooling.

Required Methods

fn load(sources: &[ConfigSource]) -> Result<Self, ConfigError>

Load this config by applying sources in order (later sources win).

The conventional source slice is:

&[
    ConfigSource::Defaults,
    ConfigSource::File(path),
    ConfigSource::Env { prefix: Some("APP".into()) },
]

fn field_meta() -> &'static [ConfigFieldMeta]

Return metadata for all fields in this config struct.

Useful for generating config file templates, shell completions, or documentation.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
