Enum LogTarget 

pub enum LogTarget {
    Stdout,
    Stderr,
    File {
        directory: PathBuf,
        filename_prefix: String,
        rotation: RotationConfig,
    },
    Multi(Vec<LogTarget>),
}

Log output target.

Variants

Stdout

Write to stdout.

Stderr

Write to stderr.

File

Write to a file with optional rotation.

Fields

directory: PathBuf

Directory to store log files.

filename_prefix: String

Filename prefix (e.g., “simulator” -> “simulator.log”).

rotation: RotationConfig

Rotation configuration.

Multi(Vec<LogTarget>)

Write to multiple targets.

Implementations

impl LogTarget

pub fn file(directory: impl Into<PathBuf>) -> LogTarget

Create a file target with default settings.

pub fn daily_file( directory: impl Into<PathBuf>, prefix: impl Into<String>, ) -> LogTarget

Create a file target with daily rotation.

pub fn hourly_file( directory: impl Into<PathBuf>, prefix: impl Into<String>, ) -> LogTarget

Create a file target with hourly rotation.

pub fn has_file_output(&self) -> bool

Check if this target includes file output.

pub fn has_console_output(&self) -> bool

Check if this target includes stdout/stderr.

Trait Implementations

impl Clone for LogTarget

fn clone(&self) -> LogTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogTarget

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

Formats the value using the given formatter.

impl Default for LogTarget

fn default() -> LogTarget

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LogTarget

fn deserialize<__D>( __deserializer: __D, ) -> Result<LogTarget, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LogTarget

fn eq(&self, other: &LogTarget) -> 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 LogTarget

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for LogTarget

impl StructuralPartialEq for LogTarget
