+//! `#[near]` and `#[near_bindgen]` documentation module
+//!
+//! This is not a real module; here we document the attributes that [`#[near]`](../attr.near.html)
+//! and [`#[near_bindgen]`](../attr.near_bindgen.html) macro use.
+
+/// Initialization Methods inner [`#[near]`](../attr.near.html) annotation. More details can be found [here](https://docs.near.org/sdk/rust/contract-structure/near-bindgen#initialization-methods)
+///
+/// By default, the `Default::default()` implementation of a contract will be used to initialize a contract. There can be a custom initialization function which takes parameters or performs custom logic with the following `#[init]` annotation:
+/// # Examples
+///
+/// ## Basic example
+///
+/// ```rust
+/// use near_sdk::{log, near};
+///
+/// #[near(contract_state)]
+/// #[derive(Default)]
+/// pub struct Counter {
+///     value: u64,
+/// }
+///
+/// #[near]
+/// impl Counter {
+///     #[init]
+///     pub fn new(value: u64) -> Self {
+///         log!("Custom counter initialization!");
+///         Self { value }
+///     }
+/// }
+/// ```
+pub fn init() {}
+
+/// Payable Methods inner [`#[near]`](../attr.near.html) annotation. More details can be found [here](https://docs.near.org/sdk/rust/contract-structure/near-bindgen#payable-methods)
+///
+/// Methods can be annotated with `#[payable]` to allow tokens to be transferred with the method invocation. For more information, see payable methods.
+///
+/// To declare a function as payable, use the `#[payable]` annotation as follows:
+/// # Examples
+///
+/// ## Basic example
+///
+/// ```rust
+///use near_sdk::near;
+///
+/// #[near(contract_state)]
+/// #[derive(Default)]
+/// pub struct Counter {
+///     val: i8,
+/// }
+///
+/// #[near]
+/// impl Counter {
+///     #[payable]
+///     pub fn my_method(&mut self) {
+///        //...
+///     }
+/// }
+/// ```
+pub fn payable() {}
+
+/// Private Methods inner [`#[near]`](../attr.near.html) annotation. More details can be found [here](https://docs.near.org/sdk/rust/contract-structure/near-bindgen#private-methods)
+///
+/// Some methods need to be exposed to allow the contract to call a method on itself through a promise, but want to disallow any other contract to call it. For this, use the `#[private]` annotation to panic when this method is called externally. See [private methods](https://docs.near.org/sdk/rust/contract-interface/private-methods) for more information.
+///
+/// This annotation can be applied to any method through the following:
+/// # Examples
+///
+/// ## Basic example
+///
+/// ```rust
+/// use near_sdk::near;
+///
+/// #[near(contract_state)]
+/// #[derive(Default)]
+/// pub struct Counter {
+///     val: u64,
+/// }
+///
+/// #[near]
+/// impl Counter {
+///     #[private]
+///     pub fn my_method(&mut self) {
+///         // ...
+///     }
+/// }
+/// ```
+pub fn private() {}
+
+/// Result serialization inner [`#[near]`](../attr.near.html) annotation.
+///
+/// Only one of `borsh` or `json` can be specified.
+///
+/// # Examples
+///
+/// ## Basic example
+///
+/// ```rust
+/// use near_sdk::near;
+///
+/// #[near(contract_state)]
+/// #[derive(Default)]
+/// pub struct Counter {
+///     val: u64,
+/// }
+///
+/// #[near]
+/// impl Counter {
+///     #[result_serializer(borsh)]
+///     pub fn add_borsh(&self, #[serializer(borsh)] _a: Vec<String>) {
+///         // ..
+///     }
+/// }
+/// ```
+pub fn result_serializer() {}
+
+/// Support Result types regardless of how they're referred to inner [`#[near]`](../attr.near.html) annotation.
+///
+/// Have `#[handle_result]` to Support Result types regardless of how they're referred to
+/// Function marked with `#[handle_result]` should return `Result<T, E> (where E implements FunctionError)`. If you're trying to use a type alias for `Result`, try `#[handle_result(aliased)]`
+///
+/// # Examples
+///
+/// ## Basic example
+///
+/// ```rust
+/// use near_sdk::{near, AccountId, Promise, PromiseError};
+///
+/// #[near(contract_state)]
+/// #[derive(Default)]
+/// pub struct Counter {
+///     val: u64,
+/// }
+///
+/// #[near]
+/// impl Counter {
+///     #[handle_result]
+///     pub fn get_result(
+///         &self,
+///         account_id: AccountId,
+///         #[callback_result] set_status_result: Result<(), PromiseError>,
+///     ) -> Result<(), &'static str> {
+///         // ..
+///         Ok(())
