Enum Error

pub enum Error {
    Undersize {
        len: usize,
        min_len: usize,
    },
    Oversize {
        len: usize,
        max_len: usize,
    },
    OutOfBoundary {
        index: usize,
        len: usize,
    },
}

Errors when confinement constraints were not met.

Variants

Undersize

Operation results in collection reduced below the required minimum number of elements.

Fields

len: usize

Current collection length

min_len: usize

Minimum number of elements which must be present in the collection

Oversize

Operation results in collection growth above the required maximum number of elements.

Fields

len: usize

Current collection length

max_len: usize

Maximum number of elements which must be present in the collection

OutOfBoundary

Attempt to address an index outside the collection bounds.

Fields

index: usize

Index which was outside the bounds

len: usize

The actual number of elements in the collection

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

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, f: &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<Error> for AsciiError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Error

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

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
