Enum ReadError

pub enum ReadError<E> {
    KeyNotFound,
    KeyTooBig,
    BufferTooSmall,
    Corrupted,
    Flash(E),
}

Error returned by ReadTransaction::read.

Variants

KeyNotFound

The requested key is not present in the database.

KeyTooBig

The requested key is larger than MAX_KEY_SIZE

BufferTooSmall

The requested key was found, but the value was larger than the provided buffer.

Corrupted

Database is corrupted, or not formatted yet.

Flash(E)

Some operation on the underlying Flash failed.

Trait Implementations

impl<E: Clone> Clone for ReadError<E>

fn clone(&self) -> ReadError<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for ReadError<E>

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

Formats the value using the given formatter.

impl<E> Format for ReadError<E>

where E: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl<E> From<Error<E>> for ReadError<E>

fn from(e: Error<E>) -> Self

Converts to this type from the input type.

impl<E: PartialEq> PartialEq for ReadError<E>

fn eq(&self, other: &ReadError<E>) -> 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.
