Dependencies

Struct Dependencies 

Source
pub struct Dependencies { /* private fields */ }
Expand description

Represents dependencies between plugins and services in the application.

The Dependencies struct is used to declare what other plugins or services a particular plugin or service depends on. This information is used during the build process to ensure proper initialization order.

§Examples

use diode::{Dependencies, Plugin, StdError};

struct DatabasePlugin;
struct ApiPlugin;

impl Plugin for DatabasePlugin {
    async fn build(&self, _app: &mut diode::AppBuilder) -> Result<(), StdError> {
        Ok(())
    }
}

impl Plugin for ApiPlugin {
    async fn build(&self, _app: &mut diode::AppBuilder) -> Result<(), StdError> {
        Ok(())
    }

    fn dependencies(&self) -> Dependencies {
        Dependencies::new().plugin::<DatabasePlugin>()
    }
}

Implementations§

Source§

impl Dependencies

Source

pub fn new() -> Self

Creates a new empty dependencies set.

§Returns

Returns a new Dependencies instance with no dependencies.

§Examples
use diode::Dependencies;

let deps = Dependencies::new();
Source

pub fn plugin<T>(self) -> Self
where T: Plugin + 'static,

Adds a plugin dependency to this dependencies set.

§Type Parameters
  • T - The plugin type to depend on. Must implement Plugin + 'static.
§Returns

Returns Self for method chaining.

§Examples
use diode::{Dependencies, Plugin, StdError};

struct DatabasePlugin;

impl Plugin for DatabasePlugin {
    async fn build(&self, _app: &mut diode::AppBuilder) -> Result<(), StdError> {
        Ok(())
    }
}

let deps = Dependencies::new().plugin::<DatabasePlugin>();
Source

pub fn merge(self, other: Dependencies) -> Self

Merges another dependencies set into this one.

§Arguments
  • other - Another Dependencies instance to merge.
§Returns

Returns Self with all dependencies from both sets.

§Examples
use diode::Dependencies;

let deps1 = Dependencies::new();
let deps2 = Dependencies::new();
let merged = deps1.merge(deps2);
