Struct Narration 

pub struct Narration { /* private fields */ }

Recordings of what films say, each found by its text. It shares the bytes, so cloning it is cheap. Give it to MoviePlayer::narration.

Implementations

impl Narration

pub fn new(bytes: &'static [u8]) -> Self

Reads what Narration::pack wrote. Bytes it does not understand hold no recordings, and the films use the system’s voice.

pub fn clip(&self, text: &str) -> Option<SoundClip>

The recording of text, if there is one.

pub fn seconds(&self, text: &str) -> Option<f64>

How long the recording of text lasts, in seconds, without decoding it.

pub fn len(&self) -> usize

How many recordings it has.

pub fn is_empty(&self) -> bool

Whether it has none.

pub fn pack(recordings: &[(String, Vec<f32>)], rate: u32) -> Vec<u8>

Packs recordings: each text with its samples, at rate a second.

pub fn pack_onto( bytes: &[u8], recordings: &[(String, Vec<f32>)], rate: u32, ) -> Vec<u8>

What Narration::pack wrote in bytes, with recordings added. What is in bytes stays exactly as it was, so that adding a few texts after a film changed keeps the takes chosen before; a text in both is the new recording. Bytes it does not understand count as no recordings.
