pub struct Global {
pub wasm_ty: WasmValType,
pub mutability: bool,
}
Expand description
A WebAssembly global.
Note that we record both the original Wasm type and the Cranelift IR type
used to represent it. This is because multiple different kinds of Wasm types
might be represented with the same Cranelift IR type. For example, both a
Wasm i64
and a funcref
might be represented with a Cranelift i64
on
64-bit architectures, and when GC is not required for func refs.
Fields§
§wasm_ty: WasmValType
The Wasm type of the value stored in the global.
mutability: bool
A flag indicating whether the value may change at runtime.
