Trait config_manager::ConfigInit

pub trait ConfigInit {
    fn parse_options(options: ConfigOptions) -> Result<Self, Error>
    where
        Self: Sized;
    fn get_command() -> Command;

    fn parse() -> Result<Self, Error>
    where
        Self: Sized,
    { ... }
}

Config trait that constructs an instance of itself from environment, command line and configuration files.

Don’t implement the trait manually, invoking #[config] is the only correct way to derive this trait.

Required Methods

fn parse_options(options: ConfigOptions) -> Result<Self, Error>where
    Self: Sized,

Takes all the environment and tries to build an instance according to the options and the structure attributes.

fn get_command() -> Command

Build clap::Command that can initialize the annotated struct.

Provided Methods

fn parse() -> Result<Self, Error>where
    Self: Sized,

Takes all the environment and tries to build an instance according to the structure attributes.
