Struct tracing_subscriber::field::delimited::VisitDelimited

pub struct VisitDelimited<D, V> { /* private fields */ }

A visitor wrapper that inserts a delimiter after the wrapped visitor formats a field value.

Implementations

impl<D, V> VisitDelimited<D, V>

pub fn new(delimiter: D, inner: V) -> Self

Returns a new Visit implementation that wraps inner so that each formatted field is separated by the provided delimiter.
