Struct screeps::JsVec

pub struct JsVec<T> { /* private fields */ }

Reference to a JavaScript array which is expected to contain a specific type of item.

All TryFrom / TryInto conversions use type checking, but FromExpectedType / IntoExpectedType possibly don’t.

The implementation for Into<Vec<T>> uses IntoExpectedType internally.

Trait notes: implements TryInto<Vec<T>>, but Vec<T> does not implement TryFrom<JsVec<T>> due to coherence issues.

Implementations

impl<T> JsVec<T>

pub fn len(&self) -> usize

impl<T> JsVec<T>where
    T: FromExpectedType<Value>,

pub fn get(&self, idx: usize) -> Option<T>

Gets an item, panicking if the types don’t match and check-all-casts is enabled.

pub fn try_get(&self, idx: usize) -> Result<Option<T>, ConversionError>

Gets an item, returning an error if the types don’t match and check-all-casts is enabled.

pub fn iter(&self) -> Iter<'_, T>

Iterates over elements, panicking if any are not the expected type and check-all-casts is enabled.

pub fn try_iter(&self) -> TryIter<'_, T>

Iterates over elements, returning an error if any are not the expected type and check-all-casts is enabled.

Use IntoIterator::into_iter to iterate expecting all types match.

pub fn try_into_iter(self) -> TryIntoIter<T>

Iterates over elements, consuming self and returning a result if any are not the expected type.

Use IntoIterator::into_iter to iterate expecting all types match.

pub fn try_local(&self) -> Result<Vec<T>, ConversionError>

Turns this remote JS array into a local Vec, returning an error if any elements are not the expected type and check-all-casts is enabled.

pub fn local(&self) -> Vec<T>

Turns this remote JS array into a local Vec, panicking if any elements are not the expected type and check-all-casts is enabled.
