Function std::str::from_c_strUnstable

pub unsafe fn from_c_str(s: *const i8) -> &'static str

Constructs a static string slice from a given raw pointer.

This function will read memory starting at s until it finds a 0, and then transmute the memory up to that point as a string slice, returning the corresponding &'static str value.

This function is unsafe because the caller must ensure the C string itself has the static lifetime and that the memory s is valid up to and including the first null byte.

Panics

This function will panic if the string pointed to by s is not valid UTF-8.
