Struct CodecOptions 

pub struct CodecOptions { /* private fields */ }

Untyped string → string bag. The over-the-wire shape of options as they travel from the caller (CLI / pipeline JSON / FFI) to a codec factory.

Insertion order is preserved and iter walks keys in the order they were set. Duplicate keys overwrite (last writer wins).

Implementations

impl CodecOptions

pub fn new() -> Self

pub fn set(self, k: impl Into<String>, v: impl Into<String>) -> Self

Builder-style setter, useful for one-liners. CodecOptions::new().set("interlace", "true").

pub fn insert(&mut self, k: impl Into<String>, v: impl Into<String>)

Mutating insert. Overwrites any existing entry with the same key.

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

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

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

pub fn from_json(s: &str) -> Result<Self>

Build a bag from a JSON object. Scalar values (bool / number / string) are stringified into the bag; arrays and nested objects are rejected — keys with structured values don’t map into the flat string bag.

pub fn from_json_value(v: &Value) -> Result<Self>

As from_json but takes a pre-parsed value (the shape pipelines already use — TrackSpec.codec_params).

Performs copy-assignment from source.

impl Debug for CodecOptions

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

impl Default for CodecOptions

fn default() -> CodecOptions

Returns the “default value” for a type.
