Enum Sink 

#[non_exhaustive]
pub enum Sink {
    Auto,
    Stdout,
    Stderr,
    Journald,
}

Where to write log events.

Auto (default) emits to the console when stdout is a TTY and to journald otherwise. Set KAMU_LOG_SINK (auto, stdout, stderr, journald) to override without code changes. Journald is rejected on targets without the systemd feature. On wasm32, Auto, Stdout, and Stderr all map to the JavaScript console.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

TTY → console, non-TTY → journald (on systemd) or stderr (otherwise).

Stdout

Write to stdout.

Stderr

Write to stderr.

Journald

Write to the systemd journal. Requires the systemd feature.

Implementations

impl Sink

pub fn from_env_value(value: &str) -> Self

Parse from an env-var value. Unknown values resolve to Auto.

Trait Implementations

impl Clone for Sink

fn clone(&self) -> Sink

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Sink

impl Debug for Sink

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

Formats the value using the given formatter.

impl Default for Sink

fn default() -> Sink

Returns the “default value” for a type.

impl Eq for Sink

impl PartialEq for Sink

fn eq(&self, other: &Sink) -> 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.
