Passing parameters via the URL

Passing parameters via the URL is the easiest way to pass data to the server. We can explore this concept by passing the name of a to-do item and returning that single to-do item to the client.

Before we touch the networking layer, we must build the core function that loads the data and filters for the to-do item by name which can be done with the following code:

//! File: nanoservices/to_do/core/src/api/basic_actions/get.rs
. . .
use glue::errors::{
    NanoServiceError,
    NanoServiceErrorStatus
};
. . .
pub async fn get_by_name(name: &str)
    -> Result<ToDoItem, NanoServiceError> {
    Ok(get_all_handle::<ToDoItem>()?
        .remove(name)
        .ok_or(
            NanoServiceError::new(
                format!("Item with name {} not found", name),
                NanoServiceErrorStatus::NotFound
            )
        )?
    )
}

Note that our filter at this stage is not optional, as we are loading all the data and then...
