pub enum TableInitialValue {
Null {
precomputed: Vec<FuncIndex>,
},
Expr(ConstExpr),
}
Expand description
Initial value for all elements in a table.
Variants§
Null
Initialize each table element to null, optionally setting some elements to non-null given the precomputed image.
Fields
§
precomputed: Vec<FuncIndex>
A precomputed image of table initializers for this table.
This image is constructed during try_func_table_init
and
null-initialized elements are represented with
FuncIndex::reserved_value()
. Note that this image is empty by
default and may not encompass the entire span of the table in which
case the elements are initialized to null.
Expr(ConstExpr)
An arbitrary const expression.
