fmt Layer (see docs) configuration.

Example

# declare a layer named "app"
[layer.app]
type = "fmt"
writer = "my_file" # must be a declared writer
formatter =  "pretty" # can be : "full", "compact", "pretty", "json"
span_events = "none" # can be : "new", "enter", "exit", "close", "none", "active", "full"
ansi = false # color terminal
# the following properties are optional
filter = "only_app" # must be a named filter
time = true
level = true
target = true
file = true
line_number = true
thread_ids = true
thread_names = true
span_list = true # for "json" formatter only
current_span = true # for "json" formatter only
flatten_event = true # for "json" formatter only

Fields

filter: Option<String>

Applies a per Layer filter, makes this a Filtered Layer

writer: String

Where does the output go

formatter: FmtLayerFormatter

Formatting kind/type

span_events: SpanEvents

Which span events should be recorded

ansi: bool

Ansi color escape codes (for color terminal) recommend to disable if writer is file

time: Option<bool>

Record time

level: Option<bool>

Record level

target: Option<bool>

Record span/event target

file: Option<bool>

Record source file

line_number: Option<bool>

Record source file line number

thread_ids: Option<bool>

Record thread id

thread_names: Option<bool>

Record thread name

span_list: Option<bool>

Record span list (json formatter only)

current_span: Option<bool>

Record current span (json formatter only)

flatten_event: Option<bool>

Flatten json output (json formatter only)

Trait Implementations

impl Clone for FmtLayer

fn clone(&self) -> FmtLayer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FmtLayer

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FmtLayer

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FmtLayer

fn eq(&self, other: &FmtLayer) -> 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 Serialize for FmtLayer

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for FmtLayer

impl StructuralPartialEq for FmtLayer
