Enum Utf8Error 

pub enum Utf8Error {
    InvalidCharBoundary {
        at: usize,
    },
    OutOfBounds {
        at: usize,
        len: usize,
    },
}

Error type for UTF-8 operations that indicates an invalid character boundary or out of bounds access.

Variants

InvalidCharBoundary

The index does not lie on a UTF-8 character boundary.

Fields

at: usize

The index that was not on a character boundary

OutOfBounds

The index or range is out of bounds.

Fields

at: usize

The requested index

len: usize

The length of the buffer

Trait Implementations

impl Clone for Utf8Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Utf8Error

impl Debug for Utf8Error

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

Formats the value using the given formatter.

impl Display for Utf8Error

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

Formats the value using the given formatter.

impl Eq for Utf8Error

impl Error for Utf8Error

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 From<Utf8Error> for Error

Available on crate feature std only.

fn from(value: Utf8Error) -> Self

Converts to this type from the input type.

impl PartialEq for Utf8Error

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

Equality operator ==.

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

Inequality operator !=.
