Trait IndexableValues 

pub trait IndexableValues {
    type Text: Clone;
    type Binary: Clone;

    // Required method
    fn get(&self, col_idx: usize) -> Option<Value<Self::Text, Self::Binary>>;
}

Collection of indexable values.

Required Associated Types

type Text: Clone

The string variant.

type Binary: Clone

The binary variant.

Required Methods

fn get(&self, col_idx: usize) -> Option<Value<Self::Text, Self::Binary>>

Get the value at the specified column index.

Arguments

• col_idx - The index of the column to retrieve.

Returns

The value at the specified column index, or None if the index is out of bounds.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
