Attribute Macro near_bindgen

#[near_bindgen]

This macro is deprecated. Use near instead. The difference between #[near] and #[near_bindgen] is that with #[near_bindgen] you have to manually add boilerplate code for structs and enums so that they become Json- and Borsh-serializable:

use near_sdk::{near_bindgen, NearSchema, borsh::{BorshSerialize, BorshDeserialize}};

#[near_bindgen]
#[derive(BorshSerialize, BorshDeserialize, NearSchema)]
#[borsh(crate = "near_sdk::borsh")]
struct MyStruct {
   pub name: String,
}

Instead of:

use near_sdk::near;

#[near(serializers=[borsh])]
struct MyStruct {
    pub name: String,
}
