Implementations

impl PermissionDecision

pub fn allow() -> Self

Approve the tool call as-is.

pub fn allow_with_input(updated_input: Value) -> Self

Approve the tool call with a modified input payload. The claude binary will receive the modified input in place of the model’s original.

pub fn deny(reason: impl Into<String>) -> Self

Deny the tool call. reason is forwarded to the model as feedback.

pub fn with_updated_permissions(self, updates: Vec<PermissionUpdate>) -> Self

Attach a list of PermissionUpdates to an allow decision. These are forwarded to the claude binary as updatedPermissions on the wire and applied to the session’s permission state. No-op on a deny decision - the CLI’s PermissionResultDeny has no equivalent channel.

pub fn is_allow(&self) -> bool

True if this is an allow decision.

pub fn updated_input(&self) -> Option<&Value>

For an allow decision with modified input, returns the modified input.

pub fn updated_permissions(&self) -> &[PermissionUpdate]

Permission updates attached to an allow decision. Empty slice for deny, or for an allow that carries no updates.

pub fn reason(&self) -> Option<&str>

For a deny decision, returns the reason string.
