Trait QueriableContainer 

pub trait QueriableContainer {
    type Idx;
    type SubqueryId: FieldId;

    const IDX_PLACEHOLDER: &'static str = "<idx>.";

    // Required method
    fn get_item(
        &self,
        idx: &Self::Idx,
    ) -> Option<&<Self::SubqueryId as FieldId>::Queriable>;

    // Provided method
    fn split(s: &str) -> Option<(&str, &str)> { ... }
}

Type that contains sub-queriables of the same type, individually retrieveable by some index. It is itself a Queriable.

Provided Associated Constants

const IDX_PLACEHOLDER: &'static str = "<idx>."

Required Associated Types

type Idx

type SubqueryId: FieldId

Required Methods

fn get_item( &self, idx: &Self::Idx, ) -> Option<&<Self::SubqueryId as FieldId>::Queriable>

Provided Methods

fn split(s: &str) -> Option<(&str, &str)>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
