Attribute Macro attributes 

#[attributes]

Extracts all attributes into a HashMap variable.

This attribute macro retrieves all available attributes from the request context and makes them available as a HashMap for comprehensive attribute access.

Usage

use hyperlane::*;
use hyperlane_macros::*;

#[route("/attributes")]
struct Attributes;

impl ServerHook for Attributes {
    async fn new(_ctx: &Context) -> Self {
        Self
    }

    #[response_body(&format!("request attributes: {request_attributes:?}"))]
    #[attributes(request_attributes)]
    async fn handle(self, ctx: &Context) {}
}

impl Attributes {
    #[attributes(request_attributes)]
    async fn attributes_with_ref_self(&self, ctx: &Context) {}
}

#[attributes(request_attributes)]
async fn standalone_attributes_handler(ctx: &Context) {}

The macro accepts a variable name that will contain a HashMap of all attributes. The variable will be available as a HashMap in the function scope.

Multi-Parameter Usage

use hyperlane::*;
use hyperlane_macros::*;

#[route("/multi_attrs")]
struct MultiAttrs;

impl ServerHook for MultiAttrs {
    async fn new(_ctx: &Context) -> Self {
        Self
    }

    #[response_body(&format!("attrs1: {attrs1:?}, attrs2: {attrs2:?}"))]
    #[attributes(attrs1, attrs2)]
    async fn handle(self, ctx: &Context) {}
}

The macro accepts multiple variable names separated by commas.
