Crate gotham_formdata

Expand description

This crate is an extension to the popular gotham web framework for Rust. It aims to reduce boilerplate necessary to read request bodies today as a stop-gap until gotham finally implements a body extractor.

:sparkles: Features

Parse application/x-www-form-urlencoded request bodies
Parse multipart/form-data request bodies
Verify the parsed request body
#![forbid(unsafe_code)] ensures that all functionality is implemented in 100% safe Rust code

:warning: Warning

This crate is asynchronous, but does not yet enforce uploads limits. YOU ARE RESPONSIBLE FOR ENFORCING UPLOAD LIMITS.

:spiral_notepad: Example

use gotham_formdata::FormData;
use validator::Validate;

#[derive(FormData, Validate)]
struct LoginData {
	#[validate(length(min = 5, max = 16))]
	username: String,
	#[validate(length(min = 8))]
	password: String
}

async fn login_handler(state: &mut State) -> Result<Response<Body>, HandlerError> {
	let login_data: LoginData = FormData::parse_form_data(state).await?;
	Ok(if login_data.password == "secret" {
		create_response(state, StatusCode::OK, TEXT_PLAIN, login_data.username)
	} else {
		create_empty_response(state, StatusCode::FORBIDDEN)
	})
}

:label: Versioning

Like all rust crates, this crate will follow semantic versioning guidelines. However, changing the MSRV (minimum supported rust version) is not considered a breaking change.

Modules

value

This mod defines the Value used for parsing the form data.

Enums

Error

This error type is used when parsing form data from a request body was unsuccessful.

Traits

FormData

This is the trait implemented by #[derive(FormData)]. It provides a method to parse the struct it is implemented for to be parsed from the request body contained in gotham’s state.

FormDataFromState

This is the equivalent of FormData from the state’s perspective. Use this if you prefer state.parse_form_data::<MyData>()? over MyData::parse_form_data(&mut state)?.

Type Definitions

FormDataFuture

This is the return type of FormData::parse_form_data.

Derive Macros

FormData

This derive macro implements FormData for the struct it is invoked on. Enums, unions and tuple structs are not supported.
