Trait SafeOption 

pub trait SafeOption<T> {
    // Required methods
    fn safe_get(&self) -> Result<&T, ErrorInfo>;
    fn safe_get_msg<S: Into<String>>(&self, msg: S) -> Result<&T, ErrorInfo>;
    fn ok_msg(self, err: impl Into<String>) -> Result<T, ErrorInfo>;
}

Required Methods

fn safe_get(&self) -> Result<&T, ErrorInfo>

fn safe_get_msg<S: Into<String>>(&self, msg: S) -> Result<&T, ErrorInfo>

fn ok_msg(self, err: impl Into<String>) -> Result<T, ErrorInfo>

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.
