Struct StyleHints 

pub struct StyleHints {
    pub version: u32,
    pub properties: Vec<PropertyStyleHint>,
    pub suggested_playback_seconds: Option<u32>,
    pub layer_hint: Option<String>,
}

Optional build-time “style hints” block: per-property statistics plus archive-level rendering defaults, computed by the opt-in stt-build --style-hints profiler so a fresh dataset renders sensibly without hand-tuning.

Hints are DEFAULTS — a renderer or user can always override them. The whole block is additive: archives without it (and readers that don’t know it) are unaffected.

Fields

version: u32

Style-hints block schema version. Currently 1.

properties: Vec<PropertyStyleHint>

Per-property statistics (numeric percentiles or categorical cardinality — see PropertyStyleHint).

suggested_playback_seconds: Option<u32>

Suggested playback duration in seconds: clamp(round(sqrt(bucket_count)), 20, 90) where bucket_count is the time-range duration divided by temporal_bucket_ms. Absent when the bucket size is unknown/zero.

layer_hint: Option<String>

Dominant produced layer kind: one of "points", "paths", "trips", or "polygons" (absent when no kind could be derived). Kept as a string (not an enum) so a newer writer’s vocabulary can’t fail an older reader’s decode.

Trait Implementations

impl Clone for StyleHints

fn clone(&self) -> StyleHints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StyleHints

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StyleHints

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StyleHints

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

impl Serialize for StyleHints

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
