Struct RateClass 

pub struct RateClass {
    pub content_hz: u16,
    pub adapt_hz: u16,
    pub max_stale_ms: u16,
}

The declared content, adaptation, and staleness timing envelope.

Fields

content_hz: u16

Content refresh cadence in hertz.

adapt_hz: u16

Adapter loop cadence in hertz.

max_stale_ms: u16

Maximum stale data age accepted by the surface.

Implementations

impl RateClass

pub fn safe_default() -> Self

Safe fallback for missing rate metadata.

pub fn watch() -> Self

Low-rate watch-style envelope.

pub fn hud() -> Self

HUD-style envelope for low-bandwidth visual overlays.

pub fn stereo() -> Self

Stereo display envelope for rich pose-coupled surfaces.

pub fn to_expr(self) -> Expr

Encodes this envelope as an open rate map.

pub fn from_expr(expr: &Expr) -> Result<Self, RateError>

Parses a rate map.

pub fn from_optional_expr(expr: Option<&Expr>) -> Result<Self, RateError>

Parses an optional rate map, using RateClass::safe_default when it is absent.
