Trait NotFound 

pub trait NotFound<T> {
    // Required method
    fn is_not_found(&self) -> bool;
}

Classifies results that contain the crate’s not-found error family.

Successful results and unrelated errors are not classified as missing. Classification delegates to Error::is_not_found.

Required Methods

fn is_not_found(&self) -> bool

Reports whether the result contains a not-found error.

An Ok value always returns false. Other error variants also return false without changing the result.

Dyn Compatibility

This trait is dyn compatible.

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