Enum TrunSamples 

pub enum TrunSamples {
    Inherited {
        count: u32,
        first_flags: Option<u32>,
    },
    Explicit(Vec<TrunEntry>),
}

The samples of a trun box.

A run without any per-sample field is stored as a count, so decoding never allocates in proportion to an untrusted sample_count. Use TrunSamples::iter to visit every sample’s TrunEntry in either form.

Variants

Inherited

Every sample inherits its duration, size, flags, and composition offset from tfhd/trex, except that the first sample may override its flags.

Fields

count: u32

first_flags: Option<u32>

Explicit(Vec<TrunEntry>)

Per-sample entries, used when the run carries at least one per-sample field.

Implementations

impl TrunSamples

pub fn len(&self) -> usize

The number of samples in the run.

pub fn is_empty(&self) -> bool

pub fn get(&self, index: usize) -> Option<TrunEntry>

The entry of the sample at index, or None if it is out of range.

pub fn iter(&self) -> TrunSamplesIter<'_>

Each sample’s entry in order, without allocating.
