Struct BSTR

pub struct BSTR(/* private fields */);

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.

type DefaultType = BSTR

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

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

fn ok(value: &Self::DefaultType) -> Result<Self, Error>

Converts from Self::DefaultType to Result<T>.

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>

Safety

fn drop_param(_: &mut Param<'_, Self>)

impl Clone for BSTR

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BSTR

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BSTR

fn default() -> Self

Returns the “default value” for a type.

impl Display for BSTR

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for BSTR

fn drop(&mut self)

Executes the destructor for this type.

impl From<&String> for BSTR

fn from(value: &String) -> Self

Converts to this type from the input type.

impl From<&str> for BSTR

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for BSTR

fn from(value: String) -> Self

Converts to this type from the input type.

impl PartialEq<&str> for BSTR

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<BSTR> for &str

fn eq(&self, other: &BSTR) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<String> for BSTR

fn eq(&self, other: &String) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<str> for BSTR

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for BSTR

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> TryFrom<&'a BSTR> for String

type Error = FromUtf16Error

The type returned in the event of a conversion error.

fn try_from(value: &BSTR) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<BSTR> for String

type Error = FromUtf16Error

The type returned in the event of a conversion error.

fn try_from(value: BSTR) -> Result<Self, Self::Error>

Performs the conversion.
