Trait IntoResult 

pub trait IntoResult {
    type Value;
    type Error;

    // Required method
    fn into_result(self) -> Result<Self::Value, Self::Error>;
}

Tells the bind macro whether the given expression yielded a bindable value or an error.

Enables the bind macro to determine by representing the value yielded by the given expression as Result whether to create a variable and bind it to the value, or to call the optional error handler and evaluate the execution flow control block.

Implemented by default for Result and Option, with () as Error for the latter.

For the usage example, refer to the bind macro documentation, which includes an example of using it with user-defined types.

Required Associated Types

type Value

Type of the value that the bind macro binds the created variable to.

type Error

Type of the error that the bind macro passes as the only argument to the optional error handler.

Required Methods

fn into_result(self) -> Result<Self::Value, Self::Error>

Represents the yielded value as Result
