Function share_grants 

pub fn share_grants(
    workspace: &str,
    sharer: &str,
    share: &str,
    node: &TreePath,
    access: ShareAccess,
) -> Result<Vec<Grant>, ShareRefusal>

The grants sharer gives the workspace workspace by sharing node with access, under the share id share (unique per share, such as the id of the message that shares it).

Errors

ShareRefusal::Id for a malformed id and ShareRefusal::Node for a node that is not one record or one item of it in workspace.
