Expand description

Represents options for canonical function definitions.

Variants§

§

UTF8

The string types in the function signature are UTF-8 encoded.

§

UTF16

The string types in the function signature are UTF-16 encoded.

§

CompactUTF16

The string types in the function signature are compact UTF-16 encoded.

§

Memory(u32)

The memory to use if the lifting or lowering of a function requires memory access.

The value is an index to a core memory.

§

Realloc(u32)

The realloc function to use if the lifting or lowering of a function requires memory allocation.

The value is an index to a core function of type (func (param i32 i32 i32 i32) (result i32)).

§

PostReturn(u32)

The post-return function to use if the lifting of a function requires cleanup after the function returns.
