Expand description

Trait for extracting data from the full request (including body)

This is used for extractors that consume the request body.

§Example: Implementing a custom extractor that consumes the body

use rustapi_core::FromRequest;
use rustapi_core::{Request, ApiError, Result};
use std::future::Future;

struct PlainText(String);

impl FromRequest for PlainText {
    async fn from_request(req: &mut Request) -> Result<Self> {
        // Ensure body is loaded
        req.load_body().await?;
         
        // Consume the body
        if let Some(bytes) = req.take_body() {
            if let Ok(text) = String::from_utf8(bytes.to_vec()) {
                return Ok(PlainText(text));
            }
        }
         
        Err(ApiError::bad_request("Invalid plain text body"))
    }
}
