#[repr(C)]
pub union ValRaw {
/* private fields */
}
Expand description
A “raw” and unsafe representation of a WebAssembly value.
This is provided for use with the Func::new_unchecked
and
Func::call_unchecked
APIs. In general it’s unlikely you should be using
this from Rust, rather using APIs like Func::wrap
and TypedFunc::call
.
This is notably an “unsafe” way to work with Val
and it’s recommended to
instead use Val
where possible. An important note about this union is that
fields are all stored in little-endian format, regardless of the endianness
of the host system.
Implementations§
source§impl ValRaw
impl ValRaw
sourcepub fn null() -> ValRaw
pub fn null() -> ValRaw
Create a null reference that is compatible with any of
{any,extern,func}ref
.
sourcepub fn get_funcref(&self) -> *mut c_void
pub fn get_funcref(&self) -> *mut c_void
Gets the WebAssembly funcref
value
sourcepub fn get_externref(&self) -> u32
pub fn get_externref(&self) -> u32
Gets the WebAssembly externref
value
sourcepub fn get_anyref(&self) -> u32
pub fn get_anyref(&self) -> u32
Gets the WebAssembly anyref
value
