Options for the ZADD command

Implementations

impl SortedSetAddOptions

pub fn add_only() -> Self

Sets the NX option for the ZADD command Only add a member if it does not already exist.

pub fn update_only(conditional_update: Option<UpdateCheck>) -> Self

Sets the XX option and optionally the GT/LT option for the ZADD command Only update existing members

pub fn add_or_update(conditional_update: Option<UpdateCheck>) -> Self

Optionally sets the GT/LT option for the ZADD command Add new member or update existing

pub fn include_changed_count(self) -> Self

Sets the CH option for the ZADD command Return the number of elements changed (not just added).

pub fn increment_score(self) -> Self

Sets the INCR option for the ZADD command Increment the score of the member instead of setting it.

Trait Implementations

impl Clone for SortedSetAddOptions

fn clone(&self) -> SortedSetAddOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for SortedSetAddOptions

fn default() -> SortedSetAddOptions

Returns the “default value” for a type.

impl ToRedisArgs for SortedSetAddOptions

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.
