Trait TryGetableArray 

pub trait TryGetableArray: Sized {
    // Required method
    fn try_get_by<I>(
        res: &QueryResult,
        index: I,
    ) -> Result<Vec<Self>, TryGetError>
       where I: ColIdx;
}

An interface to get an array of values from the query result. A type can only implement ActiveEnum or TryGetableFromJson, but not both. A blanket impl is provided for TryGetableFromJson, while the impl for ActiveEnum is provided by the DeriveActiveEnum macro. So as an end user you won’t normally touch this trait.

Required Methods

fn try_get_by<I>(res: &QueryResult, index: I) -> Result<Vec<Self>, TryGetError>

where I: ColIdx,

Just a delegate

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.
