Trait FromHttpContext 

pub trait FromHttpContext:
    Sized
    + Send
    + 'static {
    // Required method
    fn from_http_context<'life0, 'async_trait>(
        ctx: &'life0 dyn IHttpContext,
    ) -> Pin<Box<dyn Future<Output = Result<Self>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Trait for constructing a request struct from the HTTP context.

Implemented automatically by the #[get], #[post], #[put], #[delete] proc macros for request types. Custom implementations are also supported.

Automatic implementation

For POST/PUT/PATCH routes, the macro will attempt serde_json::from_slice on the request body. For GET/DELETE routes with path parameters, the macro will extract parameters from ctx.request().route_params() by field name.

Manual implementation

#[async_trait::async_trait]
impl FromHttpContext for MyRequest {
    async fn from_http_context(ctx: &dyn IHttpContext) -> Result<Self> {
        // custom construction logic
    }
}

Required Methods

fn from_http_context<'life0, 'async_trait>( ctx: &'life0 dyn IHttpContext, ) -> Pin<Box<dyn Future<Output = Result<Self>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
