[−][src]Struct zombiezen_const_cstr::ConstCStr
A reference to a C-compatible string constant.
Implementations
impl ConstCStr
[src]
pub const unsafe fn from_str_with_nul_unchecked(val: &'static str) -> ConstCStr
[src]
Unsafely creates a constant C string reference from a string slice.
Prefer using the const_cstr!
macro than calling this function directly.
Safety
The provided slice must be NUL-terminated and not contain any interior NUL bytes.
Examples
use zombiezen_const_cstr::ConstCStr; let s = unsafe { ConstCStr::from_str_with_nul_unchecked("foo\0") }; assert_eq!(s.as_str(), "foo");
pub fn as_str(self) -> &'static str
[src]
Returns the referenced string without the terminating NUL byte.
pub fn as_bytes(self) -> &'static [u8]
[src]
Returns the referenced string as a byte slice without the terminating NUL byte.
pub const fn as_bytes_with_nul(self) -> &'static [u8]
[src]
Returns the referenced string as a byte slice, with the NUL terminating byte.
pub const fn as_ptr(self) -> *const c_char
[src]
Returns a pointer to the beginning of the string constant.
Suitable for passing to any function that expects a C-compatible string.
Since the underlying string is guaranteed to be 'static
,
the pointer should always be valid.
pub fn as_cstr(self) -> &'static CStr
[src]
Returns &'static CStr
to the referenced string.
