Struct Rule 

#[non_exhaustive]
pub struct Rule {
    pub action: Option<Action>,
    pub condition: Option<Condition>,
    /* private fields */
}

A lifecycle Rule, combining an action to take on an object and a condition which will trigger that action.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

action: Option<Action>

Optional. The action to take.

condition: Option<Condition>

Optional. The condition(s) under which the action will be taken.

Implementations

impl Rule

pub fn new() -> Self

pub fn set_action<T>(self, v: T) -> Self

where T: Into<Action>,

Sets the value of action.

pub fn set_or_clear_action<T>(self, v: Option<T>) -> Self

where T: Into<Action>,

Sets or clears the value of action.

pub fn set_condition<T>(self, v: T) -> Self

where T: Into<Condition>,

Sets the value of condition.

pub fn set_or_clear_condition<T>(self, v: Option<T>) -> Self

where T: Into<Condition>,

Sets or clears the value of condition.

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rule

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Rule

fn default() -> Rule

Returns the “default value” for a type.

impl Message for Rule

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Rule

fn eq(&self, other: &Rule) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
