Function provwasm_std::add_attribute

pub fn add_attribute<H: Into<Addr>, S: Into<String>, B: Into<Binary>>(
    address: H,
    name: S,
    value: B,
    value_type: AttributeValueType
) -> StdResult<CosmosMsg<ProvenanceMsg>>

Create a message that will add an attribute (a typed key-value pair) to an account.

Example

// Imports required
use cosmwasm_std::{Binary, Env, Addr, Response, StdResult};
use provwasm_std::{add_attribute, AttributeValueType, ProvenanceMsg};

// Add a greeting attribute to an account.
// NOTE: The name below must resolve to the contract address.
fn exec_add_greeting(
    env: Env,
    address: Addr,
    text: String,
) -> StdResult<Response<ProvenanceMsg>> {
    let attr_name = String::from("greeting.my-contract.sc.pb");
    let greeting = String::from("hello");
    let msg = add_attribute(
        address,
        &attr_name,
        Binary::from(greeting.as_bytes()),
        AttributeValueType::String,
    )?;
    let mut res = Response::new().add_message(msg);
    Ok(res)
}
