Enum CharBoundaryError

pub enum CharBoundaryError {
    InputEmpty,
    IndexOutOfRange(usize, usize),
    NotUTF8Boundary(usize),
}

An Error for char_boundary_* functions, see their documentation for more info.

Variants

InputEmpty

Indicates that a given input was empty.

IndexOutOfRange(usize, usize)

Indicates that the given index was out of range of a given length.

NotUTF8Boundary(usize)

Indicates that the given index was not on a utf-8 sequence boundary.

Trait Implementations

impl Debug for CharBoundaryError

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

Formats the value using the given formatter.

impl Display for CharBoundaryError

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

Formats the value using the given formatter.

impl Error for CharBoundaryError

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.

impl PartialEq for CharBoundaryError

fn eq(&self, other: &CharBoundaryError) -> 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.
