Struct Deserializer 

pub struct Deserializer<R> { /* private fields */ }

A structure for deserializing into Rust values using the VICI protocol.

Example

use anyhow::Result;
use serde::Deserialize;
use std::collections::BTreeMap;

fn main() -> Result<()> {
    let input = vec![
        3, 4, b'k', b'e', b'y', b'1', 0, 6, b'v', b'a', b'l', b'u', b'e', b'1',
        3, 4, b'k', b'e', b'y', b'2', 0, 6, b'v', b'a', b'l', b'u', b'e', b'2',
    ];
    let mut de = serde_vici::Deserializer::from_slice(&input);
    let value = BTreeMap::deserialize(&mut de)?;

    assert_eq!(
        value,
        {
            let mut object = BTreeMap::new();
            object.insert("key1", "value1");
            object.insert("key2", "value2");
            object
        }
    );
    Ok(())
}

Implementations

impl<'de, R> Deserializer<R>

where R: Read<'de>,

pub fn new(read: R) -> Self

Creates a VICI deserializer from one of the possible serde_vici input sources.

Typically it is more convenient to use either of the following methods instead:

• Deserializer::from_reader
• Deserializer::from_slice

impl<R> Deserializer<IoRead<R>>

where R: Read,

pub fn from_reader(reader: R) -> Self

Creates a VICI deserializer from an io::Read.

impl<'a> Deserializer<SliceRead<'a>>

pub fn from_slice(slice: &'a [u8]) -> Self

Creates a VICI deserializer from a &[u8].
