Trait OptionNodeResultExt 

pub trait OptionNodeResultExt<T> {
    // Required methods
    fn unwrap2(self) -> T;
    fn expect2(self, message: impl AsRef<str>) -> T;
    fn flatten(self) -> Option<T>;
}

Useful trait to unwrap an Option<NodeResult<'tree, T>>

Required Methods

fn unwrap2(self) -> T

Unwrap the Option and then NodeResult, panic if either is None/Err.

fn expect2(self, message: impl AsRef<str>) -> T

Unwrap the Option and then NodeResult, panic with the message if either is None/Err.

fn flatten(self) -> Option<T>

Flatten into an Option, with None if the node is present but an incorrect kind.

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.
