Struct screeps::memory::MemoryReference

pub struct MemoryReference(_);

A Reference to a screeps memory object

Methods

impl MemoryReference

pub fn new() -> Self

pub unsafe fn from_reference_unchecked(reference: Reference) -> Self

Creates a MemoryReference from some JavaScript reference.

Warning: MemoryReference is only designed to work with "plain" JavaScript objects, and passing an array or a non-plain object into this method probably won't be what you want. MemoryReference also gives access to all properties, so if this is indeed a plain object, all of its values should also be plain objects.

Passing a non-plain-object reference into this function won't invoke undefined behavior in and of itself, but other functions can rely on MemoryReference being "plain".

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

pub fn f64(&self, key: &str) -> Result<Option<f64>, ConversionError>

pub fn path_f64(&self, path: &str) -> Result<Option<f64>, ConversionError>

pub fn i32(&self, key: &str) -> Result<Option<i32>, ConversionError>

pub fn path_i32(&self, path: &str) -> Result<Option<i32>, ConversionError>

pub fn string(&self, key: &str) -> Result<Option<String>, ConversionError>

pub fn path_string(&self, path: &str) -> Result<Option<String>, ConversionError>

pub fn dict(
    &self,
    key: &str
) -> Result<Option<MemoryReference>, ConversionError>

pub fn path_dict(
    &self,
    path: &str
) -> Result<Option<MemoryReference>, ConversionError>

pub fn dict_or_create(
    &self,
    key: &str
) -> Result<MemoryReference, UnexpectedTypeError>

Get a dictionary value or create it if it does not exist.

If the value exists but is a different type, this will return None.
