Struct TableInitialization

source
pub struct TableInitialization {
    pub initial_values: PrimaryMap<DefinedTableIndex, TableInitialValue>,
    pub segments: Vec<TableSegment>,
}
Expand description

Table initialization data for all tables in the module.

Fields§

§initial_values: PrimaryMap<DefinedTableIndex, TableInitialValue>

Initial values for tables defined within the module itself.

This contains the initial values and initializers for tables defined within a wasm, so excluding imported tables. This initializer can represent null-initialized tables, element-initialized tables (e.g. with the function-references proposal), or precomputed images of table initialization. For example table initializers to a table that are all in-bounds will get removed from segment and moved into initial_values here.

§segments: Vec<TableSegment>

Element segments present in the initial wasm module which are executed at instantiation time.

These element segments are iterated over during instantiation to apply any segments that weren’t already moved into initial_values above.
