Struct Params 

pub struct Params {
    pub time_gap: f64,
    pub alpha: f64,
    pub interaction_range: f64,
    pub interaction_strength: f64,
    pub wall_range: f64,
    pub wall_strength: f64,
    pub arrival_radius: f64,
}

Parameters for the Collision-Free Speed model.

Fields

time_gap: f64

Safety time gap (s). Larger values produce more conservative walkers.

alpha: f64

Direction blending weight on the desired (goal) direction.

interaction_range: f64

Interaction range for neighbour repulsion (m).

interaction_strength: f64

Interaction strength for neighbour repulsion (dimensionless).

wall_range: f64

Wall interaction range (m).

wall_strength: f64

Wall interaction strength (dimensionless).

arrival_radius: f64

Arrival radius (m). See social_force::Params::arrival_radius. Default: 0.3 m.

Implementations

impl Params

pub fn validate(&self, dt: f64) -> Result<(), CrowdError>

Validate this parameter set against dt.

CFS is a first-order kinematic model: speeds are directly clamped from the collision-free headroom, so there is no explicit-Euler CFL condition to check. Validation therefore focuses on strictly-positive ranges and a finite positive dt.

Trait Implementations

impl Clone for Params

fn clone(&self) -> Params

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Params

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

Formats the value using the given formatter.

impl Default for Params

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Params

fn eq(&self, other: &Params) -> 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 Copy for Params

impl StructuralPartialEq for Params
