Function to_value

pub fn to_value<T>(value: &T) -> Result<Value, Error>
where
    T: Serialize,

Serialize an instance of type T to a Firestore Value.

Examples

#[derive(serde::Serialize)]
struct T {
    b: bool,
    n: i64,
}
assert_eq!(
    to_value(&T { b: true, n: 1 })?,
    Value {
        value_type: Some(ValueType::MapValue(MapValue {
            fields: std::collections::HashMap::from([
                (
                    "b".to_string(),
                    Value {
                        value_type: Some(ValueType::BooleanValue(true))
                    }
                ),
                (
                    "n".to_string(),
                    Value {
                        value_type: Some(ValueType::IntegerValue(1))
                    }
                )
            ])
        }))
    }
