Implementations§

§

impl<'a, T> Serializer<'a, T>
where T: Target,

pub fn new(target: T) -> Serializer<'a, T>

Create a new application/x-www-form-urlencoded serializer for the given target.

If the target is non-empty, its content is assumed to already be in application/x-www-form-urlencoded syntax.

pub fn for_suffix(target: T, start_position: usize) -> Serializer<'a, T>

Create a new application/x-www-form-urlencoded serializer for a suffix of the given target.

If that suffix is non-empty, its content is assumed to already be in application/x-www-form-urlencoded syntax.

pub fn clear(&mut self) -> &mut Serializer<'a, T>

Remove any existing name/value pair.

Panics if called after .finish().

pub fn encoding_override( &mut self, new: Option<&'a dyn Fn(&str) -> Cow<'_, [u8]>> ) -> &mut Serializer<'a, T>

Set the character encoding to be used for names and values before percent-encoding.

pub fn append_pair(&mut self, name: &str, value: &str) -> &mut Serializer<'a, T>

Serialize and append a name/value pair.

Panics if called after .finish().

pub fn append_key_only(&mut self, name: &str) -> &mut Serializer<'a, T>

Serialize and append a name of parameter without any value.

Panics if called after .finish().

pub fn extend_pairs<I, K, V>(&mut self, iter: I) -> &mut Serializer<'a, T>
where I: IntoIterator, <I as IntoIterator>::Item: Borrow<(K, V)>, K: AsRef<str>, V: AsRef<str>,

Serialize and append a number of name/value pairs.

This simply calls append_pair repeatedly. This can be more convenient, so the user doesn’t need to introduce a block to limit the scope of Serializer’s borrow of its string.

Panics if called after .finish().

pub fn extend_keys_only<I, K>(&mut self, iter: I) -> &mut Serializer<'a, T>
where I: IntoIterator, <I as IntoIterator>::Item: Borrow<K>, K: AsRef<str>,

Serialize and append a number of names without values.

This simply calls append_key_only repeatedly. This can be more convenient, so the user doesn’t need to introduce a block to limit the scope of Serializer’s borrow of its string.

Panics if called after .finish().

pub fn finish(&mut self) -> <T as Target>::Finished

If this serializer was constructed with a string, take and return that string.

use form_urlencoded;
let encoded: String = form_urlencoded::Serializer::new(String::new())
    .append_pair("foo", "bar & baz")
    .append_pair("saison", "Été+hiver")
    .finish();
assert_eq!(encoded, "foo=bar+%26+baz&saison=%C3%89t%C3%A9%2Bhiver");

Panics if called more than once.
