Enum Command 

pub enum Command {
    Set(SetCommand),
    Get {
        delete: bool,
    },
    Increment {
        amount: Numeric,
        saturating: bool,
    },
    Decrement {
        amount: Numeric,
        saturating: bool,
    },
    Delete,
}

Commands for a key-value store.

Variants

Set(SetCommand)

Set a key/value pair.

Get

Get the value from a key.

Fields

delete: bool

Remove the key after retrieving the value.

Increment

Increment a numeric key. Returns an error if the key cannot be deserialized to the same numeric type as amount. If saturating is true, overflows will be prevented and the value will remain within the numeric bounds.

Fields

amount: Numeric

The amount to increment by.

saturating: bool

If true, the result will be constrained to the numerical bounds of the type of amount.

Decrement

Decrement a numeric key. Returns an error if the key cannot be deserialized to the same numeric type as amount. If saturating is true, overflows will be prevented and the value will remain within the numeric bounds.

Fields

amount: Numeric

The amount to increment by.

saturating: bool

If true, the result will be constrained to the numerical bounds of the type of amount.

Delete

Delete a key.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command
