Helper for constructing a Message

Thanks to the blanket implementation impl<'a, T: MessageBase> From<&'a T> for Message<'a>, implementors of this trait can be converted to a message for free.

Required Methods§

Source

fn message_title(&self) -> Cow<'_, str>

Returns the main caption of the message.

Source

fn main_annotation(&self) -> Annotation<'_>

Returns an annotation to be the first in the message.

Provided Methods§

Source

fn message_type(&self) -> AnnotationType

Returns the type of the entire message.

The default implementation returns AnnotationType::Error.

Source

fn additional_annotations<'a, T: Extend<Annotation<'a>>>( &'a self, results: &mut T, )

Adds additional annotations to the given container.

The default implementation does nothing.

Source

fn footers(&self) -> Vec<Footer<'_>>

Returns footers that are included in the message.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
