Struct FromUtf16Error

pub struct FromUtf16Error(/* private fields */);

A possible error value when converting a String from a UTF-16 byte slice.

This type is the error type for the from_utf16 method on String.

Examples

// 𝄞mu<invalid>ic
let v = &[0xD834, 0xDD1E, 0x006d, 0x0075,
          0xD800, 0x0069, 0x0063];

assert!(String::from_utf16(v).is_err());

Trait Implementations

impl Arbitrary for FromUtf16Error

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = LazyJust<FromUtf16Error, fn() -> FromUtf16Error>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( _args: <FromUtf16Error as Arbitrary>::Parameters, ) -> <FromUtf16Error as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Debug for FromUtf16Error

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

Formats the value using the given formatter.

impl Display for FromUtf16Error

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

Formats the value using the given formatter.

impl Error for FromUtf16Error

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
