Function contains_policy_id

pub fn contains_policy_id(
    asset_list: &Option<Vec<Asset>>,
    target_policy_id: &str,
) -> bool

Checks if a target policy ID exists in the asset list.

This function checks whether a specified target_policy_id exists within the provided asset_list. If the asset_list is None, the function returns false.

Arguments

• asset_list - An optional reference to a vector of Asset items.
• target_policy_id - A string slice representing the policy ID to search for.

Returns

• true - If the target policy ID exists in the asset list.
• false - If the target policy ID does not exist or the asset list is None.

Behavior

• Safely handles None values for asset_list using map_or.
• Uses iter().any() to efficiently search for a matching policy ID.
