Enum Error

#[non_exhaustive]
pub enum Error<S> {
    Storage {
        value: S,
    },
    FullStorage,
    Corrupted {},
    BufferTooBig,
    BufferTooSmall(usize),
    SerializationError(SerializationError),
    ItemTooBig,
}

The main error type

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.

Storage

An error in the storage (flash)

Fields

value: S

The error value

FullStorage

The item cannot be stored anymore because the storage is full.

Corrupted

It’s been detected that the memory is likely corrupted. You may want to erase the memory to recover.

BufferTooBig

A provided buffer was to big to be used

BufferTooSmall(usize)

A provided buffer was to small to be used (usize is size needed)

SerializationError(SerializationError)

A serialization error (from the key or value)

ItemTooBig

The item does not fit in flash, ever. This is different from Error::FullStorage because this item is too big to fit even in empty flash.

See the readme for more info about the constraints on item sizes.

Trait Implementations

impl<S: Debug> Debug for Error<S>

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

Formats the value using the given formatter.

impl<S> Display for Error<S>

where S: Display,

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

Formats the value using the given formatter.

impl<S> From<SerializationError> for Error<S>

fn from(v: SerializationError) -> Self

Converts to this type from the input type.

impl<S: PartialEq> PartialEq for Error<S>

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