[−][src]Struct tracing_subscriber::fmt::format::JsonFields
This is supported on crate feature
fmt
only.The JSON FormatFields
implementation.
Implementations
impl JsonFields
[src]
pub fn new() -> Self
[src]
This is supported on crate feature
fmt
only.Returns a new JSON FormatFields
implementation.

impl<'a> FormatFields<'a> for JsonFields
[src]
fn format_fields<R: RecordFields>(
&self,
writer: &'a mut dyn Write,
fields: R
) -> Result
[src]
&self,
writer: &'a mut dyn Write,
fields: R
) -> Result
This is supported on crate feature
fmt
only.Format the provided fields
to the provided writer
, returning a result.
fn add_fields(&self, current: &'a mut String, fields: &Record<'_>) -> Result
[src]
This is supported on crate feature
fmt
only.Record additional field(s) on an existing span.
By default, this appends a space to the current set of fields if it is
non-empty, and then calls self.format_fields
. If different behavior is
required, the default implementation of this method can be overridden.
