Struct FlowField 

pub struct FlowField {
    pub n_tokens: usize,
    pub spans: Vec<(usize, usize)>,
    pub frames: Vec<FlowFrame>,
    pub reversals: Vec<usize>,
}

The dynamics side table, keyed by byte offset.

Fields

n_tokens: usize

Token count.

spans: Vec<(usize, usize)>

Byte span per token - the byte-offset key.

frames: Vec<FlowFrame>

One frame per token.

reversals: Vec<usize>

Reversal byte offsets: where the trend flips between rising and falling.

Implementations

impl FlowField

pub fn slope_at(&self, byte: usize) -> f32

The flow slope at byte.

pub fn direction_at(&self, byte: usize) -> i8

The trend direction at byte (-1 / 0 / +1).

pub fn momentum_at(&self, byte: usize) -> u16

The trend persistence at byte: consecutive tokens up to it holding the same non-steady direction. Counts back past the caller’s span, because it is a property of the position rather than of any window over it.

Trait Implementations

impl Clone for FlowField

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlowField

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

Formats the value using the given formatter.

impl Default for FlowField

fn default() -> Self

Returns the “default value” for a type.
