Enum LogFormat 

pub enum LogFormat {
    Auto,

    Simplified,
    Json,
}

Log output format.

This chooses LogFormat::Pretty for TTY, otherwise LogFormat::Simplified.

Pretty

Pretty printing with colors.

 INFO  objectstore::http > objectstore starting

Simplified

Simplified plain text output.

Json

Dump out JSON lines.

Trait Implementations

impl Clone for LogFormat

fn clone(&self) -> LogFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogFormat

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LogFormat

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for LogFormat

type Err = FormatParseError

The associated error which can be returned from parsing.

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

impl Hash for LogFormat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for LogFormat

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

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

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