Struct SessionModes 

pub struct SessionModes { /* private fields */ }

One session’s mode, and what the client has already answered under it.

Cloneable and shared: the dispatch loop sets it while a spawned turn reads it. The lock is sync and never held across an await, for the same reason the cancellation token’s is — session/set_mode arrives during a turn, and ACP says explicitly that it may.

Implementations

impl SessionModes

pub fn new(initial: ApprovalMode) -> Self

Opens a session at initial.

A session that starts at ApprovalMode::Never offers no other mode. The other two both permit consequential work and differ only in ceremony, so moving between them is the person at the client changing their mind — the same authority they already exercise by answering a permission request. Never is a prohibition the operator set outside the protocol, and a client cannot lift what it was never given.

pub fn current(&self) -> ApprovalMode

pub fn state(&self) -> SessionModeState

The modes and the current one, as session/new and session/load report them.

pub fn set(&self, id: &SessionModeId) -> Result<ApprovalMode, ModeError>

Switches to id, returning the mode now in force.

Every “…for this session” answer is forgotten: choosing a mode is a statement about how the rest of the session should behave, and a stale allow that outlived it would be exactly the override this design exists to prevent.

Trait Implementations

impl Clone for SessionModes

fn clone(&self) -> SessionModes

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
