Enum Format

pub enum Format {
    Plain,
    Json,
}

Console subscriber log event output formats.

Currently, only Plain is supported.

Variants

Plain

Use the plain unstructured log output.

ANSI color output is enabled by default, but can be disabled at runtime by setting NO_COLOR to a non-empty value.

See: [Layer::with_ansi][tracing_subscriber::fmt::Layer::with_ansi].

Json

Use structured JSON log output.

Trait Implementations

impl Clone for Format

fn clone(&self) -> Format

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Format

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

Formats the value using the given formatter.

impl Default for Format

fn default() -> Format

Returns the “default value” for a type.

impl Display for Format

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

Formats the value using the given formatter.

impl FromStr for Format

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Format, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl PartialEq for Format

fn eq(&self, other: &Format) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&str> for Format

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Format, <Self as TryFrom<&str>>::Error>

Performs the conversion.

impl ValueEnum for Format

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
