Struct Callbacks 

pub struct Callbacks { /* private fields */ }

Provides a simple implementation of the FapiCallbacks trait.

Implementations

impl Callbacks

pub fn new<AuthFn, SignFn, BranchFn, PolicyActionFn>( auth_fn: AuthFn, sign_fn: SignFn, branch_fn: BranchFn, policy_action_fn: PolicyActionFn, ) -> Self

where AuthFn: Fn(AuthCbParam<'_>) -> Option<Cow<'static, str>> + Send + 'static, SignFn: Fn(SignCbParam<'_>) -> Option<Vec<u8>> + Send + 'static, BranchFn: Fn(BranchCbParam<'_>) -> Option<usize> + Send + 'static, PolicyActionFn: Fn(PolicyActionCbParam<'_>) -> bool + Send + 'static,

Creates a new Callbacks instance with application-defined callback functions.

Instances of this struct are registered with a FAPI context via the FapiContext::set_callbacks() function.

pub fn with_auth<F>(auth_fn: F) -> Self

where F: Fn(AuthCbParam<'_>) -> Option<Cow<'static, str>> + Send + 'static,

Creates a Callbacks instance with an application-defined auth_cb callback function.

All other callback functions will use the default implementation.

pub fn with_sign<F>(sign_fn: F) -> Self

where F: Fn(SignCbParam<'_>) -> Option<Vec<u8>> + Send + 'static,

Creates a Callbacks instance with an application-defined sign_cb callback function.

All other callback functions will use the default implementation.

pub fn with_branch<F>(branch_fn: F) -> Self

where F: Fn(BranchCbParam<'_>) -> Option<usize> + Send + 'static,

Creates a Callbacks instance with an application-defined branch_cb callback function.

All other callback functions will use the default implementation.

pub fn with_policy_action<F>(policy_action_fn: F) -> Self

where F: Fn(PolicyActionCbParam<'_>) -> bool + Send + 'static,

Creates a Callbacks instance with an application-defined policy_action_cb callback function.

All other callback functions will use the default implementation.

Trait Implementations

impl FapiCallbacks for Callbacks

fn auth_cb( &mut self, param: AuthCbParam<'_>, ) -> Result<Cow<'static, str>, Cancelled>

A callback function that allows the FAPI to request authorization values.

fn sign_cb(&mut self, param: SignCbParam<'_>) -> Result<Vec<u8>, Cancelled>

A callback function that allows the FAPI to request signatures.

fn branch_cb(&mut self, param: BranchCbParam<'_>) -> Result<usize, Cancelled>

A callback function that allows the FAPI to request branch choices.

fn policy_action_cb( &mut self, param: PolicyActionCbParam<'_>, ) -> Result<(), Cancelled>

A callback function that allows the FAPI to notify the application.
