Struct NotLoaded 

pub struct NotLoaded {
    pub model: &'static str,
    pub association: &'static str,
}

Returned when a preloadable association is accessed without first being preloaded.

Autumn never lazy-loads: if you call post.author() on a record that was not loaded with .preload(...), you get this error rather than a hidden SQL round trip.

Fields

model: &'static str

The model whose association was accessed, e.g. "Post".

association: &'static str

The association name that was accessed, e.g. "author".

Implementations

impl NotLoaded

pub const fn new(model: &'static str, association: &'static str) -> Self

Construct a NotLoaded for a model/association pair.

Trait Implementations

impl Clone for NotLoaded

fn clone(&self) -> NotLoaded

impl Eq for NotLoaded

impl Error for NotLoaded

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for NotLoaded

fn eq(&self, other: &NotLoaded) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
