FormDeserializer

Struct FormDeserializer 

Source 
pub struct FormDeserializer<'a> { /* private fields */ }
Expand description

Deserializer over a MultipartForm.

Build one with FormDeserializer::new and pass it to T::deserialize. Prefer crate::route::bind::bind_form_request, which also installs the task-local scope that file handles need.

Implementations§

Source§

impl<'a> FormDeserializer<'a>

Source

pub fn new( form: &'a MultipartForm, route_params: &'a HashMap<String, String>, ) -> FormDeserializer<'a>

Build a deserializer over form.

route_params are merged in as text values and take precedence over same-named form fields, mirroring how JSON body binding overlays path parameters.
