You can find the rustdoc here.

How to use

rust extern crate boow; use boow::Bow; // This struct contains a type for which we cannot know at compile time // whether it will be owned or borrowed. struct MyStruct<'a> { borrowed_or_owned: Bow<'a, InnerStruct>, } struct InnerStruct { _stuff: String, } impl<'a> MyStruct<'a> { // Use borrowed value fn from_borrowed(inner: &'a InnerStruct) -> Self { Self { borrowed_or_owned: Bow::Borrowed(inner) } } // Use owned value fn from_owned(inner: InnerStruct) -> Self { Self { borrowed_or_owned: Bow::Owned(inner) } } }
