Marker trait for a resource.

Required Associated Constants

const NAME: &'static [&'static str]

Name with namespace of the resource. Each part of the array is a segment in the name (i.e. MyApp.Blog.Post).

const RESOURCE_NAME: &'static str

Dot-joined resource name (e.g. "MyApp.Blog.Post").

Generated by the resource! macro as a string literal — no runtime allocation or leak() required.

const PRIMARY_KEY_GENERATED: bool

Wether the primary key of the resource is generated

Required Associated Types

type PrimaryKey: Display + DeserializeOwned + Send + Sync

Primary key type of the resource. Usually the type of the id for the resource.

type DataLayer: DataLayer<Self>

Data layer that the resource uses.

Required Methods

fn primary_key(&self) -> &Self::PrimaryKey

Mathos that returns the primary key of the resource

Provided Methods

fn before_create(&mut self)

Lifecycle hook called on every create action, after the resource is built from input but before persistence. Override to mutate the resource (e.g. set created_at timestamps).

fn before_update(&mut self)

Lifecycle hook called on every update action, after apply_update_input but before persistence. Override to mutate the resource (e.g. set updated_at timestamps).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
