Enum AutoStrategy 

pub enum AutoStrategy {
    Uuid(UuidVersion),
    Increment,
}

Strategy for automatically populating a field’s value on insert.

When a field has an AutoStrategy, Toasty generates the value automatically when a new record is created, rather than requiring the caller to supply it.

Examples

use toasty_core::schema::app::{AutoStrategy, UuidVersion};

let strategy = AutoStrategy::Uuid(UuidVersion::V4);
assert!(!strategy.is_increment());

let inc = AutoStrategy::Increment;
assert!(inc.is_increment());

Variants

Uuid(UuidVersion)

Generate a UUID of the specified version.

Increment

Use an auto-incrementing integer sequence (database-assigned).

Implementations

impl AutoStrategy

pub fn is_increment(&self) -> bool

Returns true if this strategy is AutoStrategy::Increment.

Examples

use toasty_core::schema::app::AutoStrategy;

let inc = AutoStrategy::Increment;
assert!(inc.is_increment());
