Trait nanoserde::DeJson

pub trait DeJson: Sized {
    // Required method
    fn de_json(
        state: &mut DeJsonState,
        input: &mut Chars<'_>
    ) -> Result<Self, DeJsonErr>;

    // Provided method
    fn deserialize_json(input: &str) -> Result<Self, DeJsonErr> { ... }
}

A trait for objects that can be deserialized from JSON.

Required Methods

fn de_json( state: &mut DeJsonState, input: &mut Chars<'_> ) -> Result<Self, DeJsonErr>

Parse Self from the input string.

let mut state = DeJsonState::default();
let mut chars = "42".chars();
state.next(&mut chars);
state.next_tok(&mut chars).unwrap();
let out = u32::de_json(&mut state, &mut chars).unwrap();
assert_eq!(out, 42);

Provided Methods

fn deserialize_json(input: &str) -> Result<Self, DeJsonErr>

Parse Self from the input string.

This is a convenient wrapper around de_json.

Object Safety

This trait is not object safe.
