Struct ClipMetadata 

pub struct ClipMetadata { /* private fields */ }

Schema-validated clip-level metadata constants.

Float constants compare by exact f64::to_bits() equality so this type can provide an Eq contract without changing per-frame MetadataValue comparison semantics.

Implementations

impl ClipMetadata

pub const fn new() -> ClipMetadata

Creates an empty clip metadata constant map.

pub fn get(&self, key: &str) -> Option<&MetadataValue>

Returns clip metadata constant by key.

pub fn iter(&self) -> impl Iterator<Item = (&str, &MetadataValue)>

Iterates clip metadata constants in deterministic key order.

pub fn validate(&self, schema: &MetadataSchema) -> Result<(), PixelFlowError>

Validates all clip metadata constants against a schema.

pub fn set( &mut self, schema: &MetadataSchema, key: impl Into<String>, value: MetadataValue, ) -> Result<(), PixelFlowError>

Writes a clip metadata constant after registration and type validation.

Trait Implementations

impl Clone for ClipMetadata

fn clone(&self) -> ClipMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClipMetadata

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

Formats the value using the given formatter.

impl Default for ClipMetadata

fn default() -> ClipMetadata

Returns the “default value” for a type.

impl PartialEq for ClipMetadata

fn eq(&self, other: &ClipMetadata) -> 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.
