Struct Array

Source
pub struct Array<'a> { /* private fields */ }
Expand description

An SQL array.

An eXtremeDB SQL array contains Values of the same type, and exposes public methods to access them.

A Value can only be converted into an Array if it has the Array type. The opposite conversion is always possible.

Implementations§
