Struct redis_sk::geo::Coord

pub struct Coord<T> {
    pub longitude: T,
    pub latitude: T,
}

A coordinate (longitude, latitude). Can be used with geo_pos to parse response from Redis.

T is the type of the every value.

• You may want to use either f64 or f32 if you want to perform mathematical operations.
• To keep the raw value from Redis, use String.

Fields

longitude: T

Longitude

latitude: T

Latitude

Implementations

impl<T> Coord<T>

pub fn lon_lat(longitude: T, latitude: T) -> Coord<T>

Create a new Coord with the (longitude, latitude)

Trait Implementations

impl<T: Debug> Debug for Coord<T>

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

Formats the value using the given formatter.

impl<T: FromRedisValue> FromRedisValue for Coord<T>

fn from_redis_value(v: &Value) -> RedisResult<Self>

Given a redis Value this attempts to convert it into the given destination type. If that fails because it’s not compatible an appropriate error is generated.

fn from_redis_values(items: &[Value]) -> RedisResult<Vec<Self>>

Similar to from_redis_value but constructs a vector of objects from another vector of values. This primarily exists internally to customize the behavior for vectors of tuples.

impl<T: PartialEq> PartialEq<Coord<T>> for Coord<T>

fn eq(&self, other: &Coord<T>) -> bool

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

fn ne(&self, other: &Coord<T>) -> bool

This method tests for !=.

impl<T: ToRedisArgs> ToRedisArgs for Coord<T>

fn write_redis_args<W: ?Sized>(&self, out: &mut W) where
    W: RedisWrite, 

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

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.

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).
