Enum cassandra_proto::query::QueryValues

pub enum QueryValues {
    SimpleValues(Vec<Value>),
    NamedValues(HashMap<String, Value>),
}

Enum that represents two types of query values:

• values without name
• values with names

Variants

SimpleValues(Vec<Value>)

NamedValues(HashMap<String, Value>)

Methods

impl QueryValues

pub fn with_names(&self) -> bool

It returns true if query values is with names and false otherwise.

pub fn len(&self) -> usize

It return number of values.

Trait Implementations

impl Clone for QueryValues

fn clone(&self) -> QueryValues

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueryValues

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

Formats the value using the given formatter.

impl<'a, T: Into<Value> + Clone> From<&'a [T]> for QueryValues

fn from(values: &'a [T]) -> QueryValues

It converts values from Vec to query values without names QueryValues::SimpleValues.

impl<S: ToString + Hash + Eq, V: Into<Value> + Clone> From<HashMap<S, V, RandomState>> for QueryValues

fn from(values: HashMap<S, V>) -> QueryValues

It converts values from HashMap to query values with names QueryValues::NamedValues.

impl<T: Into<Value> + Clone> From<Vec<T>> for QueryValues

fn from(values: Vec<T>) -> QueryValues

It converts values from Vec to query values without names QueryValues::SimpleValues.

impl IntoBytes for QueryValues

fn into_cbytes(&self) -> Vec<u8>

It should convert a struct into an array of bytes.
