Struct slog_logfmt::Logfmt

pub struct Logfmt<W: Write> { /* fields omitted */ }

A drain & formatter for logfmt-formatted messages.

Format

The default format looks like the somewhat-more-human-readable format in https://brandur.org/logfmt#human. You can customize it with the LogfmtBuilder method set_prefix.
