Trait Into

pub trait Into<T> {
    // Required method
    fn into(x: Self) -> T;
}

Required Methods

fn into(x: Self) -> T

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> Into<Result<T, Error>> for Result<T>

fn into(x: Self) -> JsonRpcResult<T>

impl<T: Send + Sync + 'static> Into<Pin<Box<dyn Future<Output = T> + Send>>> for BoxFuture<T>

fn into(x: Self) -> BoxFuture<T>

Implementors

impl Into<Error> for CoreError

impl<T> Into<Result<T, Error>> for CoreResult<T>

impl<T: Send + Sync + 'static> Into<Pin<Box<dyn Future<Output = Result<T, Error>> + Send>>> for CoreBoxFuture<T>

impl<T: Send + Sync + 'static> Into<Pin<Box<dyn Future<Output = Result<T, Error>> + Send>>> for CoreResult<T>

Sometimes an rpc method is implemented asynchronously, then the rpc trait definition must use BoxFuture for the return type.

This into conversion allow non-async rpc implementation method to return RpcResult straight-forward. The delegate! macro with #[into] attribute will automatically call this method to do the return type conversion.
