[−][src]Module barrel::types
Types constructor module
A Type is an enum provided to other barrel APIs in order
to generate SQL datatypes. Working with them directly is possible
but not recommended.
Instead, you can use these helper functions to construct Type enums of
different...types and constraints. Field metadata is added via chainable
factory pattern functions.
Default values
If no additional arguments are provided, some assumptions will be made about the metadata of a column type.
nullable:falseindexed:falseunique:falsedefault:Nonesize:None(which will error if size is important)
Examples
extern crate barrel;
use barrel::types::*;
// Make your own Primary key :)
let col = integer().increments(true).unique(true);
