Struct serde_urlencoded::de::Deserializer

[+] Show declaration

pub struct Deserializer<'de> { /* fields omitted */ }

[−] Expand description

A deserializer for the application/x-www-form-urlencoded format.

• Supported top-level outputs are structs, maps and sequences of pairs, with or without a given length.

• Main deserialize methods defers to deserialize_map.

• Everything else but deserialize_seq and deserialize_seq_fixed_size defers to deserialize.
