/// Suggested label to display along the form field.

/// Name of the field as it will be included in the encoded query or config
/// object.
pub name: String,
/// The minimum number of entries the array must have to be valid.
///
/// Leaving the minimum_length to 0 makes the whole field optional.

/// The maximum number of entries the array can have and still be valid.
///
/// It is None when there is no maximum number
#[serde(default, skip_serializing_if = "Option::is_none")]
pub maximum_length: Option<u32>,
/// The schema of the elements inside a row of the array.
///
/// ### Accessing row fields
///
/// The name of each QueryField inside the element_schema can be used as
/// an indexing key for a field. That means that if `element_schema` contains
/// a [TextField](crate::providers::TextField) with the name `parameter_name`,
/// then you will be able to access the value of that field using
/// `ArrayField::get(i)::get("parameter_name")` for the i-th element.
///
/// ### Serialization
///
/// For example if an array field has this `element_schema`:
/// ```rust,no_run
/// # use fiberplane_models::providers::{ArrayField, TextField, SelectField, IntegerField};
/// ArrayField::new()
/// .with_name("table")
/// .with_label("example".to_string())
/// .with_element_schema(vec![
/// TextField::new().with_name("key").into(),
/// SelectField::new().with_name("operator").with_options([
/// "<".into(),
/// ">".into(),
/// "<=".into(),
/// ">=".into(),
/// "==".into()
/// ]).into(),
/// IntegerField::new().with_name("value").into(),
/// ]);
/// ```
///
/// Then the URL-encoded serialization for the fields is expected to use
/// the bracketed-notation. This means you _can_ encode all the
/// keys in the array in any order you want. It can look like this
/// (line breaks are only kept for legibility):
/// ```txt
/// "table[0][key]=less+than&
/// table[2][operator]=%3E&
/// table[0][operator]=%3C&
/// table[2][key]=greater+than&
/// table[2][value]=10&
/// table[0][value]=12"
/// ```
///
/// or you can do the "logic" ordering too:
/// ```txt
/// "table[0][key]=less+than&
/// table[0][operator]=%3C&
/// table[0][value]=12&
/// table[1][key]=greater+than&
/// table[1][operator]=%3E&
/// table[1][value]=10"
/// ```
///
/// Note that we are allowed to skip indices.
/// Any of those 2 examples above will
/// be read as:
/// ```rust,no_run
/// # #[derive(Debug, PartialEq)]
/// # struct Row { key: String, operator: String, value: u32 }
/// # let table: Vec<Row> = vec![];
/// assert_eq!(table, vec![
/// Row {
/// key: "less than".to_string(),
/// operator: "<".to_string(),
/// value: 12,
/// },
/// Row {
/// key: "greater than".to_string(),
/// operator: ">".to_string(),
/// value: 10,
/// },
/// ]);
/// ```
///
/// ### Required row fields
///
/// Any field that is marked as `required` inside `element_schema` makes it
/// mandatory to create a valid row to the Array Field.
