Enum Utf8IndexError 

pub enum Utf8IndexError {
    InvalidCharBoundary {
        index: usize,
    },
    IndexOutOfBounds(OutOfBounds),
    RangeOutOfBounds(RangeOutOfBounds),
}

Error type for UTF-8 index and range operations.

Variants

InvalidCharBoundary

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

Fields

index: usize

The index that was not on a character boundary

IndexOutOfBounds(OutOfBounds)

A single index was outside the visible bounds.

RangeOutOfBounds(RangeOutOfBounds)

A range was reversed, overflowing, or outside the visible bounds.

Trait Implementations

impl Error for Utf8IndexError

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
