Struct gstreamer::StreamType

pub struct StreamType { /* fields omitted */ }

StreamType describes a high level classification set for flows of data in Stream objects.

Note that this is a flag, and therefore users should not assume it will be a single value. Do not use the equality operator for checking whether a stream is of a certain type.

Implementations

impl StreamType

pub const UNKNOWN: StreamType

The stream is of unknown (unclassified) type.

pub const AUDIO: StreamType

The stream is of audio data

pub const VIDEO: StreamType

The stream carries video data

pub const CONTAINER: StreamType

The stream is a muxed container type

pub const TEXT: StreamType

The stream contains subtitle / subpicture data.

Feature: v1_10

pub const fn empty() -> StreamType

Returns an empty set of flags

pub const fn all() -> StreamType

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<StreamType>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> StreamType

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> StreamType

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: StreamType) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: StreamType) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: StreamType)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: StreamType)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: StreamType)

Toggles the specified flags in-place.

pub fn set(&mut self, other: StreamType, value: bool)

Inserts or removes the specified flags depending on the passed value.
