[−][src]Struct uefi::data_types::CStr16
An UCS-2 null-terminated string
This type is largely inspired by std::ffi::CStr
, see the documentation of
CStr
for more details on its semantics.
Implementations
impl CStr16
[src]
pub unsafe fn from_ptr<'ptr>(ptr: *const Char16) -> &'ptr Self
[src]
Wraps a raw UEFI string with a safe C string wrapper
Safety
The function will start accessing memory from ptr
until the first
null byte. It's the callers responsability to ensure ptr
points to
a valid string, in accessible memory.
pub fn from_u16_with_nul(codes: &[u16]) -> Result<&Self, FromSliceWithNulError>
[src]
Creates a C string wrapper from a u16 slice
Since not every u16 value is a valid UCS-2 code point, this function must do a bit more validity checking than CStr::from_bytes_with_nul
pub unsafe fn from_u16_with_nul_unchecked(codes: &[u16]) -> &Self
[src]
Unsafely creates a C string wrapper from a u16 slice.
Safety
It's the callers responsability to ensure chars is a valid UCS-2 null-terminated string, with no interior null bytes.
pub fn as_ptr(&self) -> *const Char16
[src]
Returns the inner pointer to this C string
pub fn to_u16_slice(&self) -> &[u16]
[src]
Converts this C string to a u16 slice
pub fn to_u16_slice_with_nul(&self) -> &[u16]
[src]
Converts this C string to a u16 slice containing the trailing 0 char
pub fn iter(&self) -> CStr16Iter
[src]
Returns an iterator over this C string
