Root CPL structure — defines a complete IMF composition.

Spec-required vs Option<T> policy (FIX-7 audit)

The parser is intentionally lenient: every spec-required element that isn’t strictly necessary to construct a valid CompositionPlaylist is exposed as Option<T> (or via a default = "…" serde attribute). Missing-required-field violations are surfaced as catalogue diagnostics by the validator (validate_cpl) rather than as parse errors, so a caller can still inspect the parsed structure of a non-conformant CPL.

Field-by-field map against ST 2067-3 §6 / §7 (2013 / 2016 — the 2020 edition reuses the 2016 schema verbatim):

Field	Type	Spec status
id	ImfUuid	required §6.1 — parse error if missing
annotation	Option<…>	optional §6.2
issue_date	String	required §6.3 — parse error if missing
issuer	Option<…>	optional §6.4
creator	Option<…>	optional §6.5
content_originator	Option<…>	optional §6.6
content_title	LanguageString	required §6.7 — parse error if missing
content_kind	concrete (default)	required §6.8 — default_content_kind
content_version_list	Option<…>	optional §6.10
essence_descriptor_list	Option<…>	required per ST 2067-2 §6.1.5 —
		parser-lenient; absence is reported by
		validate_cpl as Error
edit_rate	Option<…>	required §6.13 — parser-lenient; absence
		reported by validate_cpl
total_running_time	Option<String>	optional §6.14
locale_list	Option<…>	optional §6.15
extension_properties	Option<…>	optional §6.16
composition_timecode	Option<…>	optional §6.9
segment_list	SegmentList	required §6.17 — parse error if missing
has_signer/has_signature	bool	reflect presence in raw XML (§8 signatures unparsed)
source_xml	Option<String>	retained when parsed from XML; absent for JSON-deserialised

Five fields are spec-required but stored as Option<T> (with default on the serde side) to support the parser-lenient model: content_kind (defaults via default_content_kind), content_version_list, essence_descriptor_list, edit_rate, locale_list. The validator surfaces missing-required findings against the ST 2067-3 prose.

Fields

namespace: CplNamespace

The SMPTE spec version detected from the root xmlns of the CPL XML. Set after deserialization by parse_cpl().

id: ImfUuid

annotation: Option<LanguageString>

issue_date: String

issuer: Option<LanguageString>

creator: Option<LanguageString>

content_originator: Option<LanguageString>

content_title: LanguageString

content_kind: ContentKindElement

content_version_list: Option<ContentVersionList>

essence_descriptor_list: Option<EssenceDescriptorList>

edit_rate: Option<EditRate>

total_running_time: Option<String>

locale_list: Option<LocaleList>

extension_properties: Option<ExtensionProperties>

composition_timecode: Option<CompositionTimecode>

has_signer: bool

Whether the original CPL XML contained a <Signer> element. Set by parse_cpl() from raw XML before namespace stripping.

has_signature: bool

Whether the original CPL XML contained a <Signature> element. Set by parse_cpl() from raw XML before namespace stripping.

source_xml: Option<String>

The raw CPL XML as parsed, retained so callers running through validate_cpl(&cpl) can transparently invoke the runtime-XSD validator (which needs the unparsed source). Set by parse_cpl(). None when the struct was built via JSON deserialization or manual construction.

segment_list: SegmentList

Trait Implementations

impl Debug for CompositionPlaylist

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CompositionPlaylist

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CompositionPlaylist

fn eq(&self, other: &CompositionPlaylist) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CompositionPlaylist

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
