Enum gstreamer::State

#[non_exhaustive]pub enum State {
    VoidPending,
    Null,
    Ready,
    Paused,
    Playing,
    // some variants omitted
}

The possible states an element can be in. States can be changed using Element::set_state and checked using Element::get_state.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

VoidPending

no pending state.

Null

the NULL state or initial state of an element.

Ready

the element is ready to go to PAUSED.

Paused

the element is PAUSED, it is ready to accept and process data. Sink elements however only accept one buffer and then block.

Playing

the element is PLAYING, the Clock is running and the data is flowing.

impl Ord for State

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

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<State> for State

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

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

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

This method tests for !=.

impl PartialOrd<State> for State

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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