ScrollTree = 4

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

DisplayList = 5

Log the display list after each layout

RelayoutEvent = 6

Log notifications when a relayout occurs

ProfileScriptEvents = 7

Periodically log on which events script threads spend their processing time

StyleStatistics = 8

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 = 12usize

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 TryFrom<i32> for DiagnosticsLoggingOption

type Error = TryFromPrimitiveError<DiagnosticsLoggingOption>

The type returned in the event of a conversion error.

fn try_from(number: i32) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for DiagnosticsLoggingOption

const NAME: &'static str = "DiagnosticsLoggingOption"

type Primitive = i32

type Error = TryFromPrimitiveError<DiagnosticsLoggingOption>

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>

impl Copy for DiagnosticsLoggingOption

impl StructuralPartialEq for DiagnosticsLoggingOption
