A helper trait for building complex objects with imperative conditionals in a fluent style.

Provided Methods

fn map<U>(self, f: impl FnOnce(Self) -> U) -> U

where Self: Sized,

Imperatively modify self with the given closure.

fn when(self, condition: bool, then: impl FnOnce(Self) -> Self) -> Self

where Self: Sized,

Conditionally modify self with the given closure.

fn when_else( self, condition: bool, then: impl FnOnce(Self) -> Self, else_fn: impl FnOnce(Self) -> Self, ) -> Self

where Self: Sized,

Conditionally modify self with the given closure.

fn when_some<T>( self, option: Option<T>, then: impl FnOnce(Self, T) -> Self, ) -> Self

where Self: Sized,

Conditionally unwrap and modify self with the given closure, if the given option is Some.

fn when_none<T>( self, option: &Option<T>, then: impl FnOnce(Self) -> Self, ) -> Self

where Self: Sized,

Conditionally unwrap and modify self with the given closure, if the given option is None.

Dyn Compatibility

This trait is dyn compatible.

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