Represents the limits placed on a module for compiling with the pooling instance allocation strategy.

Fields

imported_functions: u32

The maximum number of imported functions for a module (default is 1000).

imported_tables: u32

The maximum number of imported tables for a module (default is 0).

imported_memories: u32

The maximum number of imported linear memories for a module (default is 0).

imported_globals: u32

The maximum number of imported globals for a module (default is 0).

types: u32

The maximum number of defined types for a module (default is 100).

functions: u32

The maximum number of defined functions for a module (default is 10000).

tables: u32

The maximum number of defined tables for a module (default is 1).

memories: u32

The maximum number of defined linear memories for a module (default is 1).

globals: u32

The maximum number of defined globals for a module (default is 10).

table_elements: u32

The maximum table elements for any table defined in a module (default is 10000).

If a table’s minimum element limit is greater than this value, the module will fail to compile.

If a table’s maximum element limit is unbounded or greater than this value, the maximum will be table_elements for the purpose of any table.grow instruction.

memory_pages: u32

The maximum number of pages for any linear memory defined in a module (default is 160).

The default of 160 means at most 10 MiB of host memory may be committed for each instance.

If a memory’s minimum page limit is greater than this value, the module will fail to compile.

If a memory’s maximum page limit is unbounded or greater than this value, the maximum will be memory_pages for the purpose of any memory.grow instruction.

This value cannot exceed any memory reservation size limits placed on instances.
