Struct merino_cache::redis::domain::RedisSuggestions

pub(crate) struct RedisSuggestions(pub(crate) Vec<Suggestion>);

A wrapper around a Vec of Suggestions that can be inserted into and retrieved from a Redis DB.

Tuple Fields

0: Vec<Suggestion>

Trait Implementations

impl From<RedisSuggestions> for Vec<Suggestion>

fn from(val: RedisSuggestions) -> Self

Converts to this type from the input type.

impl FromRedisValue for RedisSuggestions

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]) -> Result<Vec<Self, Global>, RedisError>

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 ToRedisArgs for RedisSuggestions

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, 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.

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 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.
