Enum cdrs::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.
