An abstraction and collection of data flow

Fields

task: Vault<VecDeque<Task>>

a vector of Task, store them into directory if too many in order to lower the memory

task_tmp: Vault<Vec<Task>>

cached Taskto be used

affix: Vault<VecDeque<Affix>>

a vector of Affix

req: Vault<VecDeque<Request>>

a vector of Request

req_tmp: Vault<Vec<Request>>

cached Requestto be spawned

res: Vault<Vec<Result<Response, MetaResponse>>>

a vector of Response

entities: Vault<Vec<E>>

collected entities

errs: Vault<Vec<Result<Response, MetaResponse>>>

some parse-failed Response for manual inspection

args: ArgApp

Some argument to control the data flow

couple: Vault<HashMap<u64, Couple>>

couples of task and affix, serving as a backup when the constructed request executed failed

session_storer: Option<Box<dyn for<'a> Fn(Poly, &'a ()) -> &'a str + Send>>

periodically called to backup Poly NOTE that if None all Poly lost at runtime when interupts happens

session_loader: Option<Box<dyn Fn(&str) -> Poly + Send>>

called to load Poly at resuming session or load Task to execute NOTE that if None App Starts with new session

body_modifier: Option<Box<dyn for<'c, 'd> Fn(&'c Body, Option<&'d Body>) -> Body + Send>>

modify the body of Task, Affix in Couple return the Request’s Body if not set, just simply concat the two of them

Implementations

impl<'a, E> App<E>

pub fn new() -> Self

create an instance of App

pub fn add_actor<A>(&mut self, spd: &dyn Actor<E, A>) where
    A: Affixor + Send + 'static, 

add an Actor

pub fn session_loader(&mut self, loader: Box<dyn Fn(&str) -> Poly + Send>)

add an Session Loader

pub fn session_storer(
    &mut self,
    storer: Box<dyn for<'b> Fn(Poly, &'b ()) -> &'b str + Send>
)

add an Session Storer

pub fn body_modifier(
    &mut self,
    f: Box<dyn for<'c, 'd> Fn(&'c Body, Option<&'d Body>) -> Body + Send>
)

modify the body of Task, Affix in Couple return the Request’s Body if not set, just simply concat the two of them get the overview of App

pub async fn parse<'b>(&self, res: Response) -> (Parsed<E>, u64)

specifically, dispose a Response, handle failed or corrupt Response, and return Parsed or ParseError.

pub async fn parse_all<'b>(&mut self, mware: &'b MiddleWare<'b, E>)

parse multiple Response in App, then drive all Parsed into MiddleWare

pub async fn run<'b, C, A>(
    &'a mut self,
    spd: &'a dyn Actor<E, A>,
    middleware: &'a MiddleWare<'b, E>,
    pipeline: &'a PipeLine<'b, E, C>
) -> Result<(), Box<dyn Error>> where
    A: Affixor + Send + 'static, 

drive Dyer into running.
