tracing_subscriber::fmt::format

Struct PrettyFields

Source 
pub struct PrettyFields { /* private fields */ }
Available on crate features fmt and std and ansi only.
Expand description

An excessively pretty, human-readable MakeVisitor implementation.

Implementations§

Source§

impl PrettyFields

Source

pub fn new() -> Self

Returns a new default PrettyFields implementation.

Source

pub fn with_ansi(self, ansi: bool) -> Self

👎Deprecated since 0.3.3: Use fmt::Subscriber::with_ansi or fmt::Layer::with_ansi instead.

Enable ANSI encoding for formatted fields.
