Trait ResultExt 

pub trait ResultExt {
    type Ok;
    type Err;

    // Required method
    fn into_ec<F: FnOnce(Self::Err) -> ErrorCode>(
        self,
        f: F,
    ) -> Result<Self::Ok>;
}

Extension trait for std::result::Result.

Required Associated Types

type Ok

type Err

Required Methods

fn into_ec<F: FnOnce(Self::Err) -> ErrorCode>(self, f: F) -> Result<Self::Ok>

Turns self into an ErrorCode result by calling f when self is an error.

Consider logging the error you’re turning into an ErrorCode.

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.
