Struct QueueConfigPatch 

#[non_exhaustive]
pub struct QueueConfigPatch {
    pub action_at_item_end: Option<ActionAtItemEnd>,
    pub crossfade_settings: Option<CrossfadeSettings>,
    pub max_concurrent_loads: Option<NonZeroUsize>,
    pub playback_order: Option<PlaybackOrder>,
    pub prefetch_duration: Option<f32>,
    pub max_history_size: Option<usize>,
}

What a configuration document may say about QueueConfig.

Deserialize only, never Serialize: by the time a patch is typed its references are resolved, so it holds secrets in the clear.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

action_at_item_end: Option<ActionAtItemEnd>

crossfade_settings: Option<CrossfadeSettings>

max_concurrent_loads: Option<NonZeroUsize>

Max concurrent background prefetch loads. Default: 3.

playback_order: Option<PlaybackOrder>

prefetch_duration: Option<f32>

Lead time in seconds before EOF at which the next queued track is preloaded into the audio processor. Default: 3.5. Stays f32 seconds rather than the campaign’s humantime duration convention: the value already reaches 10 setter and 14 read call sites as a bare f32, and converting the type would only churn those for a formatting preference.

max_history_size: Option<usize>

Entries the navigation history keeps. Only explicit selections and auto-advances land there, so the default is a listening session’s worth of back-steps; the queue’s own track list is unbounded.
