Enum Notice 

pub enum Notice {
    Failure(String),
    Standing(String),
}

What the session has to tell the user about its document: why the canvas is read-only, what will be overwritten by the next save, and the load that did not work.

Two kinds, because they end differently. A standing fact stands until the fact does — dismissing “read-only” would not make the container writable. A failure happened once, so it carries an acknowledgement and is gone for the rest of the session once it is given.

Variants

Failure(String)

A failure that happened once — a container that would not open, a file that would not be written.

Standing(String)

A standing fact about the document, true until it stops being true.

Trait Implementations

impl Clone for Notice

fn clone(&self) -> Notice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Notice

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Notice

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Notice

fn eq(&self, other: &Notice) -> 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 Notice

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 Notice

impl StructuralPartialEq for Notice
