Struct Apply

pub struct Apply<'a, T: SerdeDiff> { /* private fields */ }

A deserializable structure that will apply a sequence of diff commands to the target

Examples

use serde_diff::{SerdeDiff, Diff, Apply};
use serde::{Serialize, Deserialize};
#[derive(SerdeDiff, Serialize, Deserialize, PartialEq)]
struct Test {
    a: i32,
}
let diff = Diff::serializable(&Test { a: 3 }, &Test { a: 5 });
let msgpack_data = rmp_serde::to_vec_named(&diff).expect("failed to serialize diff");
let mut deserializer = rmp_serde::Deserializer::new(msgpack_data.as_slice());
let mut target = Test { a: 4 };
Apply::apply(&mut deserializer, &mut target).expect("failed when deserializing diff");

Implementations

impl<'a, 'de, T: SerdeDiff> Apply<'a, T>

pub fn deserializable(target: &'a mut T) -> Self

Create a deserializable apply, where the given target will be changed when the resulting Apply struct is deserialized

pub fn apply<D>( deserializer: D, target: &mut T, ) -> Result<(), <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Applies a sequence of diff commands to the target, as read by the deserializer

Trait Implementations

impl<'a, 'de, T: SerdeDiff> DeserializeSeed<'de> for Apply<'a, T>

type Value = ()

The type produced by using this seed.

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

where D: Deserializer<'de>,

Equivalent to the more common Deserialize::deserialize method, except with some initial piece of data (the seed) passed in.

impl<'a, 'de, T: SerdeDiff> Visitor<'de> for Apply<'a, T>

type Value = ()

The value produced by this visitor.
