Enum LinkageType 

pub enum LinkageType {
    OriginalLayout,
    DynamicLinking {
        table_offset: u32,
        table_num_entrypoints: u32,
    },
}

Variants

OriginalLayout

Keep original layout of data segment and indirect_function_table. This will emit “gaps” in “element” and in “data” sections.

This layout is non-portable and doesn’t support dynamic module re-building/re-loading. It is useful in production, to split size of generated WASM binaries.

DynamicLinking

Replace constant offsets with GOT+offset (for memory and table access). Allocate memory and table dynamically on module loading.

This allow dynamic reloading of modules. Modules entrypoints are still located in fixed position in table.

Fields

table_offset: u32

Fixed offset for storing entrypoints.

table_num_entrypoints: u32

Number of reserved elements in the table.
