Struct Message 

#[non_exhaustive]
pub struct Message {
    pub text: String,
    pub kind: MessageKind,
    pub seconds: Option<f64>,
    pub action: Option<(String, Rc<dyn Fn()>)>,
    pub on_close: Option<Rc<dyn Fn()>>,
}

Something to tell people, which goes away by itself.

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.

text: String

What it says.

kind: MessageKind

How much it matters.

seconds: Option<f64>

How long it shows; nothing means the usual.

action: Option<(String, Rc<dyn Fn()>)>

A button on it: what it says and what it does. It closes the message.

on_close: Option<Rc<dyn Fn()>>

What happens once it goes away, by itself or closed by a person.

Implementations

impl Message

pub fn new(text: impl Into<String>, kind: MessageKind) -> Self

A message saying this.

pub fn seconds(self, seconds: f64) -> Self

Shows for this long.

pub fn action(self, label: impl Into<String>, then: impl Fn() + 'static) -> Self

A button on it, which closes the message.

pub fn on_close(self, then: impl Fn() + 'static) -> Self

Runs this once it goes away.
