[][src]Enum wasmi::ExternVal

pub enum ExternVal {
    Func(FuncRef),
    Table(TableRef),
    Memory(MemoryRef),
    Global(GlobalRef),
}

An external value is the runtime representation of an entity that can be imported or exported.

Variants

Func(FuncRef)

Function.

Table(TableRef)

Table.

Memory(MemoryRef)

Memory.

Global(GlobalRef)

Global.

Should be immutable.

Implementations

impl ExternVal[src]

pub fn as_func(&self) -> Option<&FuncRef>[src]

Get underlying function reference if this ExternVal contains a function, or None if it is some other kind.

pub fn as_table(&self) -> Option<&TableRef>[src]

Get underlying table reference if this ExternVal contains a table, or None if it is some other kind.

pub fn as_memory(&self) -> Option<&MemoryRef>[src]

Get underlying memory reference if this ExternVal contains a memory, or None if it is some other kind.

pub fn as_global(&self) -> Option<&GlobalRef>[src]

Get underlying global variable reference if this ExternVal contains a global, or None if it is some other kind.
