Struct redis_graph::NodeValue

pub struct NodeValue {
    pub id: u64,
    pub labels: Vec<String>,
    pub properties: HashMap<String, Value>,
}

Represents a Redis graph node which is an object like structure with potentially multiple named fields.

Fields

id: u64

labels: Vec<String>

properties: HashMap<String, Value>

Trait Implementations

impl Clone for NodeValue

fn clone(&self) -> NodeValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodeValue

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

Formats the value using the given formatter.

impl Default for NodeValue

fn default() -> NodeValue

Returns the “default value” for a type.

impl FromRedisValue for NodeValue

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 NodeValue

Allows property extraction on NodeValues.

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.
