Struct stdweb::web::FormData

pub struct FormData(_);

The FormData interface provides a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XMLHttpRequest.send() method. It uses the same format a form would use if the encoding type were set to "multipart/form-data".

fn from(value: FormData) -> Self

Performs the conversion.

impl Clone for FormData

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for FormData

impl PartialEq<FormData> for FormData

fn eq(&self, other: &FormData) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &FormData) -> bool

This method tests for !=.

impl Debug for FormData

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
