Trait OptionExt 

pub trait OptionExt {
    type Output;

    // Required methods
    fn unwrap_or_default_log(self) -> Self::Output;
    fn unwrap_or_else_log(
        self,
        f: impl FnOnce() -> Self::Output,
    ) -> Self::Output;
    fn unwrap_or_log(self, default: Self::Output) -> Self::Output;
}

Extension trait providing tracing alternatives to Option unwrap methods.

Required Associated Types

type Output

The type of the “present” output, intended to be T for a Option<T>.

Required Methods

fn unwrap_or_default_log(self) -> Self::Output

Returns the contained Some value, or logs at the warn level and returns a default value.

fn unwrap_or_else_log(self, f: impl FnOnce() -> Self::Output) -> Self::Output

Returns the contained Some value, or logs at the warn level and computes a default value from a closure.

fn unwrap_or_log(self, default: Self::Output) -> Self::Output

Returns the contained Some value, or logs at the warn level and returns the provided default.

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.
