Struct Utf16LeStr 

pub struct Utf16LeStr<'a> { /* private fields */ }

Borrowed UTF-16LE string data.

This is a zero-copy view into an underlying byte buffer (typically an MFT entry buffer). The bytes are interpreted as UTF-16LE code units.

Notes:

• The view is not required to be valid UTF-16. Lone surrogates are dropped when converting to UTF-8 (WTF-16 style), matching utf16-simd’s semantics.
• This type is intentionally optimized for “decode only at output time” use-cases.

Implementations

impl<'a> Utf16LeStr<'a>

pub fn from_utf16le_bytes(utf16le: &'a [u8]) -> Self

Construct a borrowed UTF-16LE string from bytes.

The slice length should be a multiple of 2. If it’s not, the trailing odd byte is ignored.

pub fn from_utf16le_bytes_until_nul(utf16le: &'a [u8]) -> Self

Construct a borrowed UTF-16LE string from bytes, truncating at the first UTF-16 NUL (0x0000) code unit, if present.

pub fn empty() -> Self

pub fn is_empty(&self) -> bool

pub fn as_utf16le_bytes(&self) -> &'a [u8]

pub fn len_units(&self) -> usize

pub fn with_utf8<R>(&self, f: impl FnOnce(&str) -> R) -> R

Execute f with a temporary UTF-8 view of this string.

This does not allocate per call (it reuses a thread-local scratch buffer), but callers must not try to re-enter Utf16LeStr conversion APIs from inside f.

pub fn to_utf8_string(&self) -> String

Allocate a UTF-8 String for this UTF-16LE data.

pub fn eq_utf8(&self, other: &str) -> bool

Compare this UTF-16LE string to a UTF-8 &str without allocating.

Fast path: if other is ASCII, compare directly against UTF-16LE bytes by requiring hi == 0 for each code unit.

pub fn eq_ignore_ascii_case(&self, other: &str) -> bool

ASCII-only case-insensitive equality against a UTF-8 &str, without allocating.

Fast path: if other is ASCII, compare directly against UTF-16LE bytes by requiring hi == 0 for each code unit and using to_ascii_lowercase() on the low byte.
