impl<T> PartialEq<TaskRef<T>> for TaskRef<T>where T: TaskQueue, T::Task: PartialEq,

source§

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

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
source§

impl<T> PartialOrd<TaskRef<T>> for TaskRef<T>where T: TaskQueue, T::Task: PartialOrd,

source§

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists. Read more

impl<T> ToRedisArgs for TaskRef<T>where T: TaskQueue, T::Task: ToRedisArgs,

Available on crate feature redis-args only.
source§

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. Read more
source§

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

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

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).
source§

fn is_single_arg(&self) -> bool

Returns an indiciation if the value contained is exactly one argument. It returns false if it’s zero or more than one. This is used in some high level functions to intelligently switch between GET and MGET variants.
