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.
Ref(RefType)
The value type is a reference.
Implementations§
source§impl ValType
impl ValType
sourcepub fn is_reference_type(&self) -> bool
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
.
sourcepub fn as_reference_type(&self) -> Option<RefType>
pub fn as_reference_type(&self) -> Option<RefType>
Get the underlying reference type, if any.
sourcepub fn is_defaultable(&self) -> bool
pub fn is_defaultable(&self) -> bool
Whether the type is defaultable, i.e. it is not a non-nullable reference type.
