Struct serde_hjson::de::Deserializer

pub struct Deserializer<Iter: Iterator<Item = u8>> { /* private fields */ }

A structure that deserializes Hjson into Rust values.

Implementations

impl<Iter> Deserializer<Iter> where
    Iter: Iterator<Item = u8>, 

pub fn new(rdr: Iter) -> Deserializer<Iter>

Creates the Hjson parser from an std::iter::Iterator.

pub fn new_for_root(rdr: Iter) -> Deserializer<Iter>

Creates the Hjson parser from an std::iter::Iterator.

pub fn end(&mut self) -> Result<()>

The Deserializer::end method should be called after a value has been fully deserialized. This allows the Deserializer to validate that the input stream is at the end or that it only has trailing whitespace.
