Struct StderrStream

pub struct StderrStream { /* private fields */ }

Used for printing logs to stderr.

Examples

Printing a log to stderr:

// Required by `StderrStream` for parsing logs
let mut formatter = LogFormatter::default();

// Enabled by default
let mut stderr_output = StderrStream::default();

// Print "Hello, World!" in a neat log format
stderr_output.out(&LogStruct::debug("Hello, World!"), &mut formatter);

Implementations

impl StderrStream

pub fn out(self, log: &LogStruct, formatter: &mut LogFormatter)

Formats the given log using a formatter and prints it to stderr.

Trait Implementations

impl Clone for StderrStream

fn clone(&self) -> StderrStream

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StderrStream

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

Formats the value using the given formatter.

impl Default for StderrStream

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StderrStream

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for StderrStream

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,

Feeds a slice of this type into the given Hasher.

impl Ord for StderrStream

fn cmp(&self, other: &StderrStream) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StderrStream

fn eq(&self, other: &StderrStream) -> 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 PartialOrd for StderrStream

fn partial_cmp(&self, other: &StderrStream) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for StderrStream

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Toggleable for StderrStream

fn enable(&mut self)

Enables the output.

fn disable(&mut self)

Disables the output.

fn is_enabled(&self) -> &bool

Returns whether the output is enabled.
