Trait OkOrErr

pub trait OkOrErr<T> {
    // Required methods
    fn ok_or_internal_err(self, reason: &'static str) -> Result<T>;
    fn ok_or_err(
        self,
        code: impl ErrorInfo + Send + Sync + 'static,
    ) -> Result<T>;
    fn ok_or_err_with(
        self,
        code: impl ErrorInfo + Send + Sync + 'static,
        reason: &'static str,
    ) -> Result<T>;
}

Utility trait to map any Option<T> to a Result<T, Box<Error>>

Required Methods

fn ok_or_internal_err(self, reason: &'static str) -> Result<T>

Transforms the option into a Result, mapping None to an internal server error

fn ok_or_err(self, code: impl ErrorInfo + Send + Sync + 'static) -> Result<T>

Transforms the option into a Result, mapping None to the given error

fn ok_or_err_with( self, code: impl ErrorInfo + Send + Sync + 'static, reason: &'static str, ) -> Result<T>

Transforms the option into a Result, mapping None to the given error with a reason

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.
