Struct TfFlags

pub struct TfFlags(/* private fields */);

Track fragment header flags

Implementations

impl TfFlags

pub const BaseDataOffsetPresent: Self

Indicates the presence of the base-data-offset field. This provides an explicit anchor for the data offsets in each track run.

pub const SampleDescriptionIndexPresent: Self

Indicates the presence of this field, which over-rides, in this fragment, the default set up in the TrackExtendsBox.

pub const DefaultSampleDurationPresent: Self

Indicates the presence of the default_sample_duration field.

pub const DefaultSampleSizePresent: Self

Indicates the presence of the default_sample_size field.

pub const DefaultSampleFlagsPresent: Self

Indicates the presence of the default_sample_flags field.

pub const DurationIsEmpty: Self

This indicates that the duration provided in either default_sample_duration, or by the default_sample_duration in the TrackExtendsBox, is empty, i.e. that there are no samples for this time interval. It is an error to make a presentation that has both edit lists in the MovieBox, and empty-duration fragments.

pub const DefaultBaseIsMoof: Self

If BaseDataOffsetPresent is set, this flag is ignored. Support for the DefaultBaseIsMoof is required under the ‘iso5’ brand, and it shall not be used in brands or compatible brands earlier than ‘iso5’.

impl TfFlags

pub const fn empty() -> Self

Get a flags value with all bits unset.

pub const fn all() -> Self

Get a flags value with all known bits set.

pub const fn bits(&self) -> u32

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

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

Convert from a bits value.

This method will return None if any unknown bits are set.

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

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: u32) -> Self

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Self>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

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

Whether any set bits in a source flags value are also set in a target flags value.

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

Whether all set bits in a source flags value are also set in a target flags value.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

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

Call insert when value is true or remove when value is false.

pub const fn intersection(self, other: Self) -> Self

The bitwise and (&) of the bits in two flags values.

pub const fn union(self, other: Self) -> Self

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: Self) -> Self

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl TfFlags

pub const fn iter(&self) -> Iter<TfFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<TfFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
