Trait Host 

pub trait Host: Send {
    // Required methods
    fn get(
        &mut self,
        key: String,
    ) -> impl Future<Output = Result<Result<Option<String>, Error>>> + Send;
    fn get_all(
        &mut self,
    ) -> impl Future<Output = Result<Result<Vec<(String, String)>, Error>>> + Send;
}

Required Methods

fn get( &mut self, key: String, ) -> impl Future<Output = Result<Result<Option<String>, Error>>> + Send

Gets a configuration value of type string associated with the key.

The value is returned as an option<string>. If the key is not found, Ok(none) is returned. If an error occurs, an Err(error) is returned.

fn get_all( &mut self, ) -> impl Future<Output = Result<Result<Vec<(String, String)>, Error>>> + Send

Gets a list of configuration key-value pairs of type string.

If an error occurs, an Err(error) is returned.

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.

Implementations on Foreign Types

impl<_T: Host + ?Sized + Send> Host for &mut _T

fn get( &mut self, key: String, ) -> impl Future<Output = Result<Result<Option<String>, Error>>> + Send

Gets a configuration value of type string associated with the key.

The value is returned as an option<string>. If the key is not found, Ok(none) is returned. If an error occurs, an Err(error) is returned.

fn get_all( &mut self, ) -> impl Future<Output = Result<Result<Vec<(String, String)>, Error>>> + Send

Gets a list of configuration key-value pairs of type string.

If an error occurs, an Err(error) is returned.
