Struct PrimaryKey

pub struct PrimaryKey<T>
where
    T: Display + 'static,
{ /* private fields */ }

Primary Key Type

The Primary Key is a column in a Table used to uniquely identify a row.

In GeekORM, it can be an i32 (default), a String, or a Uuid.

Example

Here is an example of how to use the PrimaryKey struct with an integer

use geekorm::prelude::*;

#[derive(Table, Clone, Default, serde::Serialize, serde::Deserialize)]
pub struct Users {
   pub id: PrimaryKey<i32>,
   pub username: String,
}

let user = Users {
    id: PrimaryKey::from(1),
    username: String::from("JohnDoe")
};

Here is an example of how to use the PrimaryKey struct with a String

use geekorm::prelude::*;

#[derive(Table, Clone, Default, serde::Serialize, serde::Deserialize)]
pub struct Users {
    pub id: PrimaryKey<String>,
    pub username: String,
}

let user = Users {
    id: PrimaryKey::from("1"),
    username: String::from("JohnDoe")
};

fn from(value: &PrimaryKey<String>) -> Self

Converts to this type from the input type.

impl From<&PrimaryKey<i32>> for Value

fn from(value: &PrimaryKeyInteger) -> Self

Converts to this type from the input type.

impl From<&String> for PrimaryKey<String>

fn from(value: &String) -> Self

Converts to this type from the input type.

where D: TableBuilder + Default,

fn from(value: PrimaryKey<String>) -> Self

Converts to this type from the input type.

impl From<PrimaryKey<String>> for String

fn from(value: PrimaryKey<String>) -> Self

impl<D> From<PrimaryKey<i32>> for ForeignKey<i32, D>

where D: TableBuilder + Default,
