Trait NonEmptyOrExt 

pub trait NonEmptyOrExt: Sized {
    // Required method
    fn nonempty_or_else(self, default: impl FnOnce() -> Self) -> Self;

    // Provided method
    fn nonempty_or(self, value: Self) -> Self { ... }
}

Extension trait for owned strings providing an empty-string fallback.

Required Methods

fn nonempty_or_else(self, default: impl FnOnce() -> Self) -> Self

Same as Self::nonempty_or but takes a factory function.

Provided Methods

fn nonempty_or(self, value: Self) -> Self

Return the string if it is non-empty, otherwise value.

Dyn Compatibility

This trait is not dyn compatible.

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