Struct 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_owned_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.

fn from_owned_redis_values(items: Vec<Value>) -> RedisResult<Vec<Self>>

The same as from_redis_values, but takes a Vec<Value> instead of a &[Value].

fn from_byte_vec(_vec: &[u8]) -> Option<Vec<Self>>

Convert bytes to a single element vector.

fn from_owned_byte_vec(_vec: Vec<u8>) -> RedisResult<Vec<Self>>

Convert bytes to a single element vector.

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

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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 num_of_args(&self) -> usize

Returns the number of arguments this value will generate.

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).
