BasicFormatterVisitor

Struct BasicFormatterVisitor 

pub struct BasicFormatterVisitor<'a, 'b> {
    first: bool,
    f: &'a mut Formatter<'b>,
}
Expand description

Visitor that writes an [Event] to a DLT message by flattening and pre-formatting the fields into a single string.

Use BasicEventFormatter to format an [Event] using this visitor.

Fields§
