Struct redis_graph::RelationValue

pub struct RelationValue {
    pub id: u64,
    pub rel_type: String,
    pub src_node: u64,
    pub dest_node: u64,
    pub properties: HashMap<String, Value>,
}

Represents a Redis graph relation between two nodes. Like a node it can potentially contain one or multiple named fields.

Fields

id: u64

rel_type: String

src_node: u64

dest_node: u64

properties: HashMap<String, Value>

Trait Implementations

impl Clone for RelationValue

fn clone(&self) -> RelationValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RelationValue

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

Formats the value using the given formatter.

impl Default for RelationValue

fn default() -> RelationValue

Returns the “default value” for a type.

impl FromRedisValue for RelationValue

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.

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

Convert bytes to a single element vector.

impl WithProperties for RelationValue

Allows property extraction on RelationValues.

fn get_property_value(&self, key: &str) -> Option<&Value>

Returns a raw Redis value at key.

fn get_property<T: FromRedisValue>(&self, key: &str) -> RedisResult<Option<T>>

Extracts a property Redis value at key into an Option of the desired type. Will return None in case the key did not exists. Will return an error in case the value at key failed to be parsed into T.

fn get_property_option<T: FromRedisValue>(&self, key: &str) -> Option<T>

Extracts a property Redis value at key into an Option of the desired type. Will return None in case of the key did not exist or the value at key failed to be parsed into T.
