Struct uefi::data_types::CStr16

#[repr(transparent)]
pub struct 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

pub unsafe fn from_ptr<'ptr>(ptr: *const Char16) -> &'ptr Self

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>

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

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

Returns the inner pointer to this C string

pub fn to_u16_slice(&self) -> &[u16]

Converts this C string to a u16 slice

pub fn to_u16_slice_with_nul(&self) -> &[u16]

Converts this C string to a u16 slice containing the trailing 0 char

pub fn iter(&self) -> CStr16Iter<'_>

Returns an iterator over this C string
