Trait IntoCStr

pub trait IntoCStr: Sized {
    type Temp: Deref<Target = CStr>;

    // Required methods
    fn into(self) -> Self::Temp;
    fn into_cstring(self) -> CString;
    fn len(&self) -> usize;

    // Provided methods
    fn is_empty(&self) -> bool { ... }
    unsafe fn push_to_non_null_vec(self, bs: &mut Vec<u8>) { ... }
}

Represents any type that can be converted into something that can be deref’ed to a &CStr.

Required Associated Types

type Temp: Deref<Target = CStr>

Required Methods

fn into(self) -> Self::Temp

fn into_cstring(self) -> CString

fn len(&self) -> usize

Provided Methods

fn is_empty(&self) -> bool

unsafe fn push_to_non_null_vec(self, bs: &mut Vec<u8>)

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.
