Enum Error

#[non_exhaustive]
pub enum Error {
    InvalidRange(Range<usize>),
    DataLengthExceeded(Range<usize>, usize),
    AlreadyReplaced {
        range: Range<usize>,
        is_identical: bool,
    },
    Utf8(FromUtf8Error),
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidRange(Range<usize>)

DataLengthExceeded(Range<usize>, usize)

AlreadyReplaced

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

range: Range<usize>

The location of the intended replacement.

is_identical: bool

Whether the modification exactly matches (both range and data) the one it conflicts with. Some clients may wish to simply ignore this condition.

Utf8(FromUtf8Error)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<FromUtf8Error> for Error

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
