Constant ELF_WASM_DATA

pub const ELF_WASM_DATA: &'static str = ".rodata.wasm";
Expand description

This is the name of the section in the final ELF image which contains concatenated data segments from the original wasm module.

This section is simply a list of bytes and ranges into this section are stored within a Module for each data segment. Memory initialization and passive segment management all index data directly located in this section.

Note that this implementation does not afford any method of leveraging the data.drop instruction to actually release the data back to the OS. The data section is simply always present in the ELF image. If we wanted to release the data it’s probably best to figure out what the best implementation is for it at the time given a particular set of constraints.
