ERC-721 Burnable
ERC-721 Token that can be burned (destroyed).
Usage
In order to make ERC-721 Burnable
methods “external” so that other contracts can call them, you need to implement them by yourself for your final contract as follows:
use openzeppelin_stylus::{
token::erc721::{
extensions::IErc721Burnable,
Erc721, IErc721,
},
};
sol_storage! {
#[entrypoint]
struct Erc721Example {
#[borrow]
Erc721 erc721;
}
}
#[external]
#[inherit(Erc721)]
impl Erc721Example {
pub fn burn(&mut self, token_id: U256) -> Result<(), Vec<u8>> {
// ...
self.erc721.burn(token_id).map_err(|e| e.into())
}
}
