Trait ResConv 

pub trait ResConv<T, E> {
    // Required methods
    fn into_option(self) -> Option<T>;
    fn into_result(self) -> Result<T, E>;
}

Conversions between Result and Option with optional value transformation.

Required Methods

fn into_option(self) -> Option<T>

Converts into Option<T>, dropping any error information.

fn into_result(self) -> Result<T, E>

Converts into Result<T, E>.

Errors

Returns Err(E) when the source value represents an absent or failed state.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<Input, Output, Err: Default> ResConv<Output, Err> for Option<Input>

where Input: Into<Output>,

fn into_result(self) -> Result<Output, Err>

• Transforms Some(T) into Ok(T).
• Transforms None into Err(Err::Default())

Errors

• Returns Err(Err::Default()) if self is None.
