Struct MissingComponentError 

pub struct MissingComponentError {
    pub entity_description: &'static str,
    pub entity: Entity,
    pub component: &'static str,
}

An error that occurs when we tried to access data from an entity that it doesn’t have.

This could happen because the data does not occur for this type of entity, or because the entity is not currently loaded.

If this error happened when trying to access data on a client, then it may be because the client isn’t currently in a world.

As an alias for Result<T, MissingComponentError>, you may use AzaleaResult. Using the eyre or anyhow crates may also simplify error handling in your bots.

Fields

entity_description: &'static str

Should be “Entity” or “Client”

entity: Entity

component: &'static str
