Trait ConfigType

pub trait ConfigType:
    Into<ConfigVal>
    + Clone
    + Sized {
    // Required methods
    fn from_val(val: ConfigVal) -> Self;
    fn parse(s: &str) -> Result<Self, String>;
}

A type usable as a Config.

Required Methods

fn from_val(val: ConfigVal) -> Self

Converts a type-erased enum value to this type.

Panics if the enum’s variant does not match this type.

fn parse(s: &str) -> Result<Self, String>

Parses this string slice into a ConfigType.

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.
