pub struct JsonFields { /* private fields */ }

Expand description

The JSON FormatFields implementation.

Implementations

source

impl JsonFields

source

pub fn new() -> Self

Returns a new JSON FormatFields implementation.

Trait Implementations

source

impl Debug for JsonFields

source

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more

source

impl Default for JsonFields

source

fn default() -> Self

Returns the “default value” for a type. Read more

source

impl<'a> FormatFields<'a> for JsonFields

source

fn format_fields<R: RecordFields>(
 &self,
 writer: &'a mut dyn Write,
 fields: R
) -> Result

Format the provided fields to the provided writer, returning a result.

source

fn add_fields(&self, current: &'a mut String, fields: &Record<'_>) -> Result

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.
