Rust Türü | C++ Türü |
String | rust::String |
&str | rust::Str |
CxxString | std::string |
&[T] /&mut [T] | rust::Slice |
Box<T> | rust::Box<T> |
UniquePtr<T> | std::unique_ptr<T> |
Vec<T> | rust::Vec<T> |
CxxVector<T> | std::vector<T> |
- These types can be used in the fields of shared structs and the arguments and returns of extern functions.
- Note that Rust's
String
does not map directly to std::string
. There are a few reasons for this:
std::string
does not uphold the UTF-8 invariant that String
requires.
- The two types have different layouts in memory and so can't be passed directly between languages.
std::string
requires move constructors that don't match Rust's move semantics, so a std::string
can't be passed by value to Rust.
