Attribute Macro junobuild_macros::assert_upload_asset

#[assert_upload_asset]

The assert_upload_asset function is a procedural macro attribute for asserting conditions before committing the upload of an asset. It enables you to define custom validation logic to be executed prior to an asset being committed.

Example:

#[assert_upload_asset]
fn assert_upload_asset(context: AssertUploadAssetContext) -> Result<(), String> {
    // Your assertion logic here
}

When no attributes are provided, the assertion logic is applied to any asset upload within any collection. You can scope the assertion to a particular list of collections.

Example:

#[assert_upload_asset(collections = ["assets"])]
fn juno_assert_upload_asset(context: AssertUploadAssetContext) -> Result<(), String> {
    // Your assertion logic here, specific to the "assets" collection
}

The attributes accept a list of comma-separated collections. If the attribute array is left empty, the assertion will always be evaluated.
