Struct CsiWindow 

pub struct CsiWindow {
    pub window_id: WindowId,
    pub session_id: SessionId,
    pub source_id: SourceId,
    pub start_ns: u64,
    pub end_ns: u64,
    pub frame_count: u32,
    pub mean_amplitude: Vec<f32>,
    pub phase_variance: Vec<f32>,
    pub motion_energy: f32,
    pub presence_score: f32,
    pub quality_score: f32,
}

A bounded window of frames, summarized into per-subcarrier statistics plus scalar motion / presence / quality scores.

Invariants (enforced by the DSP windowing stage, CsiWindow::validate):

• all frames came from one source_id and one session_id
• start_ns < end_ns
• 0.0 <= presence_score <= 1.0 and 0.0 <= quality_score <= 1.0
• mean_amplitude.len() == phase_variance.len()

Fields

window_id: WindowId

Window id.

session_id: SessionId

Owning session.

source_id: SourceId

Source the frames came from.

start_ns: u64

Timestamp of the first frame, ns.

end_ns: u64

Timestamp of the last frame, ns.

frame_count: u32

Number of frames aggregated.

mean_amplitude: Vec<f32>

Mean amplitude per subcarrier.

phase_variance: Vec<f32>

Phase variance per subcarrier.

motion_energy: f32

Scalar motion energy (>= 0).

presence_score: f32

Presence score in [0.0, 1.0].

quality_score: f32

Window quality in [0.0, 1.0].

Implementations

impl CsiWindow

pub fn duration_ns(&self) -> u64

Duration covered by the window, ns.

pub fn subcarrier_count(&self) -> usize

Number of subcarriers summarized.

pub fn validate(&self) -> Result<(), WindowError>

Check the aggregate invariants.

Trait Implementations

impl Clone for CsiWindow

fn clone(&self) -> CsiWindow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CsiWindow

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CsiWindow

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CsiWindow

fn eq(&self, other: &CsiWindow) -> 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 CsiWindow

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
