Struct Path 

pub struct Path<T>(pub T);

Extractor for path parameters.

Extracts typed parameters from the request path. The type must implement serde::Deserialize and be stored in extensions by routing middleware.

Examples

Single Parameter

use wsforge::prelude::*;
use serde::Deserialize;

#[derive(Deserialize)]
struct UserId(u64);

async fn get_user(Path(UserId(id)): Path<UserId>) -> Result<String> {
    Ok(format!("Getting user {}", id))
}

Multiple Parameters

use wsforge::prelude::*;
use serde::Deserialize;

#[derive(Deserialize)]
struct RoomParams {
    room_id: String,
    user_id: u64,
}

async fn join_room(Path(params): Path<RoomParams>) -> Result<String> {
    Ok(format!("User {} joining room {}", params.user_id, params.room_id))
}

Tuple Fields

Trait Implementations

impl<T: DeserializeOwned + Send + Sync + Clone + 'static> FromMessage for Path<T>

fn from_message<'life0, 'life1, 'life2, 'life3, 'async_trait>( _message: &'life0 Message, _conn: &'life1 Connection, _state: &'life2 AppState, extensions: &'life3 Extensions, ) -> Pin<Box<dyn Future<Output = Result<Self>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Extracts Self from the message and context.
