Enum RuntimeError

pub enum RuntimeError {
    KeyExists,
    KeyNotFound,
    ResizeNeeded,
    TableNotFound,
    Io(Error),
}

Errors that occur after successful Env::open.

There are no errors for:

1. Missing tables
2. (De)serialization

as cuprate_database upholds the invariant that:

1. All tables exist
2. (De)serialization never fails

Variants

KeyExists

The given key already existed in the database.

KeyNotFound

The given key did not exist in the database.

ResizeNeeded

The database memory map is full and needs a resize.

Invariant

This error can only occur if Env::MANUAL_RESIZE is true.

TableNotFound

The given table did not exist in the database.

Io(Error)

A std::io::Error.

Trait Implementations

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

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

Formats the value using the given formatter.

impl Error for RuntimeError

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 RuntimeError

fn from(error: Error) -> Self

Panics

This will panic on unrecoverable errors for safety.

impl From<Error> for RuntimeError

fn from(source: Error) -> 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.
