Implementations

impl BSTR

pub fn new() -> Self

Create an empty BSTR.

This function does not allocate memory.

pub fn is_empty(&self) -> bool

Returns true if the string is empty.

pub fn len(&self) -> usize

Returns the length of the string.

pub fn from_wide(value: &[u16]) -> Self

Create a BSTR from a slice of 16-bit characters.

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

Get the string as 16-bit characters.

Trait Implementations

impl Abi for BSTR

type Abi = *mut u16

The abi representation of the implementing type.

fn set_abi(&mut self) -> *mut *mut u16

Returns a pointer for setting the object’s value via an ABI call.

fn abi(&self) -> Self::Abi

Casts the Rust object to its ABI type without copying the object.

unsafe fn from_abi(abi: Self::Abi) -> Result<Self, Error>

Casts the ABI representation to a Rust object by taking ownership of the bits.
