Expand description

Represents the types of values in a WebAssembly module.

Variants

`I32`

The value type is i32.

`I64`

The value type is i64.

`F32`

The value type is f32.

`F64`

The value type is f64.

`V128`

The value type is v128.

`FuncRef`

The value type is a function reference.

`ExternRef`

The value type is an extern reference.

Implementations

source

impl ValType

source

pub fn is_reference_type(&self) -> bool

Returns whether this value type is a “reference type”.

Only reference types are allowed in tables, for example, and with some instructions. Current reference types include funcref and externref.
