Trait EnvVariable

pub trait EnvVariable {
    type Type: ?Sized + ToOwned + Debug;

    // Required methods
    fn get_value(
        session: &Session,
        key: impl AsRef<str>,
    ) -> Result<<Self::Type as ToOwned>::Owned>;

Trait bound for Session::get_server_var() and Session::set_server_var()

Required Associated Types

type Type: ?Sized + ToOwned + Debug

Required Methods

fn get_value( session: &Session, key: impl AsRef<str>, ) -> Result<<Self::Type as ToOwned>::Owned>

fn set_value( session: &Session, key: impl AsRef<str>, val: &Self::Type, ) -> Result<()>

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.
