Variants

StyleTree

Log the DOM after each restyle

RuleTree

Log the rule tree

FlowTree

Log the fragment tree after each layout

StackingContextTree

Log the stacking context tree after each layout

ScrollTree

Log the scroll tree (the hierarchy of scrollable areas) after each layout

DisplayList

Log the display list after each layout

RelayoutEvent

Log notifications when a relayout occurs

ProfileScriptEvents

Periodically log on which events script threads spend their processing time

StyleStatistics

Log the the hit/miss statistics for the style sharing cache after each restyle

GcProfile

Log garbage collection passes and their durations

ProgressiveWebMetrics

Log Progressive Web Metrics

Implementations

impl DiagnosticsLoggingOption

pub fn help_option(&self) -> &str

Returns a string representation of this variant that is compatible with FromStr::from_str and DiagnosticsLogging::extend_from_string. This value can be used as a command-line argument for an application.

pub fn help_message(&self) -> &str

Returns a string with a short description of the diagnostic option. This value can be used as a command-line argument description for an application.

pub fn iter() -> impl Iterator<Item = Self>

Returns an Iterator that can be used to iterate over all the diagnostic options supported by Servo. This is useful when constructing a help message that enumerates all possible diagnostic flags and their respective help messages.

Trait Implementations

impl AsRef<str> for DiagnosticsLoggingOption

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for DiagnosticsLoggingOption

fn clone(&self) -> DiagnosticsLoggingOption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiagnosticsLoggingOption

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

Formats the value using the given formatter.

impl Display for DiagnosticsLoggingOption

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

Formats the value using the given formatter.

impl EnumCount for DiagnosticsLoggingOption

const COUNT: usize = 11usize

impl EnumMessage for DiagnosticsLoggingOption

fn get_message(&self) -> Option<&'static str>

fn get_detailed_message(&self) -> Option<&'static str>

fn get_documentation(&self) -> Option<&'static str>

Get the doc comment associated with a variant if it exists.

fn get_serializations(&self) -> &'static [&'static str]

impl FromStr for DiagnosticsLoggingOption

type Err = ParseError

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this type.

impl IntoEnumIterator for DiagnosticsLoggingOption

type Iterator = DiagnosticsLoggingOptionIter

fn iter() -> DiagnosticsLoggingOptionIter

impl PartialEq for DiagnosticsLoggingOption

fn eq(&self, other: &DiagnosticsLoggingOption) -> 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 TryFrom<&str> for DiagnosticsLoggingOption

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from( s: &str, ) -> Result<DiagnosticsLoggingOption, <Self as TryFrom<&str>>::Error>

Performs the conversion.

impl Copy for DiagnosticsLoggingOption

impl StructuralPartialEq for DiagnosticsLoggingOption
