Struct Preconditions 

pub struct Preconditions {
    pub bools: HashMap<String, bool>,
    pub floats_gte: HashMap<String, f32>,
    pub floats_lte: HashMap<String, f32>,
    pub floats_gt: HashMap<String, f32>,
    pub floats_lt: HashMap<String, f32>,
}

The preconditions an action requires to be applicable.

Fields

bools: HashMap<String, bool>

floats_gte: HashMap<String, f32>

Key must be >= threshold.

floats_lte: HashMap<String, f32>

Key must be <= threshold.

floats_gt: HashMap<String, f32>

Key must be > threshold.

floats_lt: HashMap<String, f32>

Key must be < threshold.

Implementations

impl Preconditions

pub fn new() -> Self

pub fn require_bool(self, key: &str, value: bool) -> Self

pub fn require_float_gte(self, key: &str, min: f32) -> Self

pub fn require_float_lte(self, key: &str, max: f32) -> Self

pub fn require_float_gt(self, key: &str, min: f32) -> Self

pub fn require_float_lt(self, key: &str, max: f32) -> Self

pub fn satisfied_by(&self, state: &WorldState) -> bool

Returns true if state satisfies all preconditions.

Trait Implementations

impl Clone for Preconditions

fn clone(&self) -> Preconditions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Preconditions

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

Formats the value using the given formatter.

impl Default for Preconditions

fn default() -> Preconditions

Returns the “default value” for a type.
