Trait MaybeExt 

pub trait MaybeExt: Sized {
    // Provided methods
    fn maybe(
        self,
        bool: impl Into<bool>,
        then: impl FnOnce(Self) -> Self,
    ) -> Self { ... }
    fn map<T>(self, data: Option<T>, then: impl FnOnce(Self, T) -> Self) -> Self { ... }
}

Methods for applying changes to an element conditionally.

Provided Methods

fn maybe(self, bool: impl Into<bool>, then: impl FnOnce(Self) -> Self) -> Self

Apply then to the element only when the condition is true.

fn map<T>(self, data: Option<T>, then: impl FnOnce(Self, T) -> Self) -> Self

Apply then to the element only when the Option is Some, passing the inner value.

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.
