Function cstr_as_str

Source
pub unsafe fn cstr_as_str(ptr: *const c_char) -> &'static str
Expand description

Convert a C string pointer into a string slice.

§Safety

  • Assumes ptr is a valid C string pointer.
  • The returned slice is only valid while the original C string remains allocated.
  • Caller must ensure the C string outlives any usage of the returned slice.

The actual lifetime is tied to the C string’s allocation lifetime. This is acceptable because this function is only used for immediate consumption within FFI call boundaries where the C string remains valid.

This function is designed for immediate consumption within FFI calls. Do not store the returned slice for use beyond the current function scope.

§Panics

Panics if ptr is null or contains invalid UTF-8.
