Enum CodeUnitStringError 

pub enum CodeUnitStringError {
    TooLong {
        len: usize,
        max: usize,
    },
    LoneSurrogate(InvalidSurrogate),
}

Failure to construct or project an exact code-unit string.

Variants

TooLong

The requested code-unit count cannot be represented by an allocation.

Fields

len: usize

Requested number of code units.

max: usize

Maximum supported number of code units.

LoneSurrogate(InvalidSurrogate)

The unit sequence contains an unpaired surrogate.

Trait Implementations

impl Clone for CodeUnitStringError

fn clone(&self) -> CodeUnitStringError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CodeUnitStringError

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

Formats the value using the given formatter.

impl Display for CodeUnitStringError

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

impl Eq for CodeUnitStringError

impl Error for CodeUnitStringError

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

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

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

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.
