Struct Stem 

pub struct Stem {
    pub id: String,
    pub label: String,
    pub url: String,
}

One separated stem of a clip, as listed by the free, read-only stems endpoint.

A stem is itself a full clip object: the listing returns the same shape as the library feed, so each stem carries its own clip id, a title whose trailing parenthetical is the stem label (e.g. "My Song (Vocals)"), a status, and a public audio_url on cdn1.suno.ai that downloads free and unauthenticated. Listing and downloading stems never spends credits or triggers separation.

Fields

id: String

The stem’s own server clip id. Used both as the stable per-stem key and to render the stem’s lossless WAV through the free convert_wav flow.

label: String

The stem label, preferring the structured metadata.stem_type_group_name (normalised, e.g. Backing_Vocals -> Backing Vocals) and falling back to the trailing parenthetical of the stem clip’s title. May be blank when neither is present, so it is never used alone as a key or name.

url: String

The public CDN MP3 URL the stem downloads from (a plain GET; free).

Trait Implementations

impl Clone for Stem

fn clone(&self) -> Stem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stem

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

Formats the value using the given formatter.

impl Eq for Stem

impl PartialEq for Stem

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