Enum Error 

pub enum Error {
    NotEmpty,
    Format,
    Configuration,
    Corrupt,
    TooLarge,
    Capacity,
    InvalidKey,
    InvalidRange,
}

A rejected operation. Returned errors never publish a partial mutation.

Variants

NotEmpty

Creation requires a fresh, zero-sized memory.

Format

Memory does not contain this tree’s format.

Configuration

Stored configuration or comparator identity differs from the caller.

Corrupt

Invalid page, pointer, length, checksum, or tree geometry.

TooLarge

An input exceeds the configured key or value bound.

Capacity

The backing memory refused growth or arithmetic capacity was exhausted.

InvalidKey

The comparator rejected malformed input.

InvalidRange

The lower bound follows the upper bound.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

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 Eq for Error

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 PartialEq for Error

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
