Struct Consequences 

pub struct Consequences {
    pub undo: Option<Consequence>,
    pub redo: Option<Consequence>,
}

What the two history buttons stand over this frame: which entry each would take, and what taking it costs the log. None is an empty stack, which draws the button dead rather than hiding it.

Fields

undo: Option<Consequence>

redo: Option<Consequence>

Implementations

impl Consequences

pub fn history(&self) -> History

Trait Implementations

impl Clone for Consequences

fn clone(&self) -> Consequences

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Consequences

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

Formats the value using the given formatter.

impl Default for Consequences

fn default() -> Consequences

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Consequences

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Consequences

fn eq(&self, other: &Consequences) -> 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.

impl Serialize for Consequences

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Consequences
