Struct SparseSetFunctions

pub struct SparseSetFunctions {
    pub contains: FunctionIdx,
    pub insert: FunctionIdx,
}

This struct contains the sparse set functions

Fields

contains: FunctionIdx

insert: FunctionIdx

Implementations

impl SparseSetFunctions

pub fn new(ctx: &mut CompileContext, layout: &SparseSetLayout) -> Self

Register all the sparse set functions and save their FunctionIdxs.

fn contains_fn(layout: &SparseSetLayout) -> Function

Returns a WASM function that will check whether a given state ID is present in the set or not.

If it is present, it returns 1, else it returns 0

fn insert_fn(layout: &SparseSetLayout, contains: FunctionIdx) -> Function

Returns a WASM function that will insert the state ID value into this set and return 1 if the given state ID was not previously in this set.

This operation is idempotent. If the given value is already in this set, then this is a no-op.

Trait Implementations

impl Debug for SparseSetFunctions

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

Formats the value using the given formatter.
