pub enum ExpireOption {
    NONE,
    NX,
    XX,
    GT,
    LT,
}

Helper enum that is used to define option for the hash expire commands

NX

NX – Only set expiration only when the field has no expiration.

GT

GT – Only set expiration only when the new expiration is greater than current one.

Trait Implementations

impl Clone for ExpireOption

fn clone(&self) -> ExpireOption

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ToRedisArgs for ExpireOption

fn write_redis_args<W>(&self, out: &mut W)

where W: ?Sized + RedisWrite,

This writes the value into a vector of bytes. Each item is a single argument. Most items generate a single item.

fn to_redis_args(&self) -> Vec<Vec<u8>>

This converts the value into a vector of bytes. Each item is a single argument. Most items generate a vector of a single item.

fn describe_numeric_behavior(&self) -> NumericBehavior

Returns an information about the contained value with regards to it’s numeric behavior in a redis context. This is used in some high level concepts to switch between different implementations of redis functions (for instance INCR vs INCRBYFLOAT).

fn num_of_args(&self) -> usize

Returns the number of arguments this value will generate.
