Trait AttributeRead

Source

pub trait AttributeRead: SealedAttributeRead {
    type Value: Value;
}

Expand description

Selects one Attribute or AttributeMap instance for Client::get_attributes.

Since 1.31.0.

Attribute<T> and AttributeMapInstance<T> implement this trait. References to them and LazyLock statics that hold them also implement it. Create an AttributeMapInstance with AttributeMap::instance. Applications cannot implement this trait. See Client::get_attributes for an example.

An AttributeMapLoad from AttributeMap::load is not a read, so it does not compile:

use dex_sdk::{AttributeMap, Client};

fn read_note(client: &Client, notes: &AttributeMap<String>) -> dex_sdk::SdkResult<()> {
    client.get_attributes("order-1", (&notes.load("n1"),))?;
    Ok(())
}
