Struct Metadata 

pub struct Metadata {
    pub title: Option<String>,
    pub author: Option<String>,
    pub subject: Option<String>,
    pub keywords: Vec<String>,
    pub creator: Option<String>,
    pub producer: Option<String>,
    pub created_at: Option<String>,
    pub modified_at: Option<String>,
    pub custom: BTreeMap<String, String>,
}

Scene-level metadata. Carried through to exports when the target format supports it (PDF document info dict, MP4 meta box, etc).

producer and creator are intentionally distinct, mirroring PDF’s /Info dictionary:

• creator — the tool that authored the source content (e.g. the NLE, drawing app, or word processor the user worked in).
• producer — the tool that wrote the output file (this crate / oxideav exporter).

Fields

title: Option<String>

author: Option<String>

subject: Option<String>

keywords: Vec<String>

creator: Option<String>

Authoring application — the tool used to create the source content. Distinct from producer; PDF’s /Info dictionary has separate /Creator and /Producer keys for the same reason.

producer: Option<String>

Producing tool name — the writer that emitted the output file.

created_at: Option<String>

ISO-8601 string; not parsed here so exporters can pass it through unchanged.

modified_at: Option<String>

ISO-8601 modification timestamp. Mirrors created_at; PDF /Info has both /CreationDate and /ModDate, mp4 mvhd has both creation_time and modification_time, etc.

custom: BTreeMap<String, String>

Extensible per-format extras. Lets callers carry metadata the standard fields don’t cover: PDF /Info custom keys, Matroska ContentTrack tags, RDF properties, mp4 udta items not covered by the standard fields, ID3 frames, and so on. Keys are case-sensitive; uniqueness is the caller’s responsibility (the map enforces it).

impl Default for Metadata

fn default() -> Metadata

Returns the “default value” for a type.
