Struct gstreamer::DebugCategory

pub struct DebugCategory(_);

This is the struct that describes the categories. Once initialized with GST_DEBUG_CATEGORY_INIT, its values can’t be changed anymore.

Implementations

impl DebugCategory

pub fn new(
    name: &str,
    color: DebugColorFlags,
    description: Option<&str>
) -> DebugCategory

pub fn get(name: &str) -> Option<DebugCategory>

pub fn threshold(self) -> DebugLevel

Returns the threshold of a DebugCategory.

Returns

the DebugLevel that is used as threshold.

pub fn set_threshold(self, threshold: DebugLevel)

Sets the threshold of the category to the given level. Debug information will only be output if the threshold is lower or equal to the level of the debugging message.

Do not use this function in production code, because other functions may change the threshold of categories as side effect. It is however a nice function to use when debugging (even from gdb).

level

the DebugLevel threshold to set.

pub fn reset_threshold(self)

Resets the threshold of the category to the default level. Debug information will only be output if the threshold is lower or equal to the level of the debugging message. Use this function to set the threshold back to where it was after using set_threshold().

pub fn above_threshold(self, level: DebugLevel) -> bool

pub fn color(self) -> DebugColorFlags

Returns the color of a debug category used when printing output in this category.

Returns

the color of the category.

pub fn name<'a>(self) -> &'a str

Returns the name of a debug category.

Returns

the name of the category.

pub fn description<'a>(self) -> Option<&'a str>

Returns the description of a debug category.

Returns

the description of the category.

Trait Implementations

impl Clone for DebugCategory

fn clone(&self) -> DebugCategory

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DebugCategory

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

Formats the value using the given formatter.

impl FromGlibPtrFull<*mut GstDebugCategory> for DebugCategory

unsafe fn from_glib_full(ptr: *mut GstDebugCategory) -> Self

Safety

impl FromGlibPtrNone<*mut GstDebugCategory> for DebugCategory

unsafe fn from_glib_none(ptr: *mut GstDebugCategory) -> Self

Safety

impl GlibPtrDefault for DebugCategory

type GlibType = *mut GstDebugCategory

impl PartialEq<DebugCategory> for DebugCategory

fn eq(&self, other: &DebugCategory) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
