Struct Score 

pub struct Score { /* private fields */ }

Available on crate feature seasonal-season-10 only.

An reference to a javascript object representing a Score, which appears randomly around the map and adds to your score when stepped on by one of your creeps.

Implementations

impl Score

pub fn score(&self) -> u32

The amount of Score that this object is worth when collected by a creep.

Screeps documentation

impl Score

pub fn ticks_to_decay(&self) -> u32

The number of ticks until the Score will decay, disappearing completely.

Screeps documentation

Methods from Deref<Target = RoomObject>

pub fn js_pos(&self) -> RoomPosition

Gets the RoomPosition of an object, which is a reference to an object in the javascript heap. In most cases, you’ll likely want a native Position instead of using this function (see HasPosition::pos), there may be cases where this can provide some slight performance benefits due to reducing object churn in the js heap, so this is kept public.

Screeps documentation

pub fn room(&self) -> Option<Room>

A link to the room that the object is currently in, or None if the object is a power creep not spawned on the current shard, or a flag or construction site not in a visible room.

Methods from Deref<Target = JsValue>

pub const NULL: JsValue

pub const UNDEFINED: JsValue

pub const TRUE: JsValue

pub const FALSE: JsValue

pub fn as_f64(&self) -> Option<f64>

Returns the f64 value of this JS value if it’s an instance of a number.

If this JS value is not an instance of a number then this returns None.

pub fn is_string(&self) -> bool

Tests whether this JS value is a JS string.

pub fn as_string(&self) -> Option<String>

If this JS value is a string value, this function copies the JS string value into Wasm linear memory, encoded as UTF-8, and returns it as a Rust String.

To avoid the copying and re-encoding, consider the JsString::try_from() function from js-sys instead.

If this JS value is not an instance of a string or if it’s not valid utf-8 then this returns None.

UTF-16 vs UTF-8

JavaScript strings in general are encoded as UTF-16, but Rust strings are encoded as UTF-8. This can cause the Rust string to look a bit different than the JS string sometimes. For more details see the documentation about the str type which contains a few caveats about the encodings.

pub fn as_bool(&self) -> Option<bool>

Returns the bool value of this JS value if it’s an instance of a boolean.

If this JS value is not an instance of a boolean then this returns None.

pub fn is_null(&self) -> bool

Tests whether this JS value is null

pub fn is_undefined(&self) -> bool

Tests whether this JS value is undefined

pub fn is_null_or_undefined(&self) -> bool

Tests whether this JS value is null or undefined

pub fn is_symbol(&self) -> bool

Tests whether the type of this JS value is symbol

pub fn is_object(&self) -> bool

Tests whether typeof self == "object" && self !== null.

pub fn is_array(&self) -> bool

Tests whether this JS value is an instance of Array.

pub fn is_function(&self) -> bool

Tests whether the type of this JS value is function.

pub fn is_bigint(&self) -> bool

Tests whether the type of this JS value is bigint.

pub fn js_typeof(&self) -> JsValue
