Struct RlpProxy 

pub struct RlpProxy(/* private fields */);

A proxy for more refined manipulation of data when deserializing.

Here is an example about how to use it.

 #[derive(Serialize, Deserialize, PartialEq, Eq, Debug)]
#[serde(from = "RlpProxy")]
enum Classify {
    Zero(u8),
    One(u8),
    Ten((u8, u8))
}
 
impl From<RlpProxy> for Classify {
    fn from(proxy: RlpProxy) -> Self {
        let raw = proxy.raw();
        let mut tree = proxy.rlp_tree();
        if tree.value_count() == 2 {
            return Classify::Ten(from_bytes(raw).unwrap())
        }
 
        let val = tree.next().unwrap()[0];
        match val {
            0 => Classify::Zero(0),
            1 => Classify::One(1),
            _ => panic!("Value Error.")
        }
    }
}

Implementations

impl RlpProxy

pub fn raw(&self) -> &[u8]

pub fn rlp_tree(&self) -> RlpTree<'_>

Trait Implementations

impl Clone for RlpProxy

fn clone(&self) -> RlpProxy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RlpProxy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RlpProxy

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RlpProxy

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
