hg-core: remove the `Operation` trait
There is no way to currently define a trait which can both return references
to `self` and to passed data, which is what we would need.
Generic Associated Types may fix this and allow us to have a unified interface.
See: rust #44265
Differential Revision: https://phab.mercurial-scm.org/D8862
//! A distinction is made between operations and commands.
//! An operation is what can be done whereas a command is what is exposed by
//! the cli. A single command can use several operations to achieve its goal.
mod dirstate_status;
mod find_root;
pub use find_root::{FindRoot, FindRootError, FindRootErrorKind};
// TODO add an `Operation` trait when GAT have landed (rust #44265):
// there is no way to currently define a trait which can both return
// references to `self` and to passed data, which is what we would need.
