Struct Processor 

pub struct Processor<'a> { /* private fields */ }

Available on crate feature processor only.

WASM module processor encapsulating processing options.

Implementations

impl<'a> Processor<'a>

pub fn set_ref_table(&mut self, name: impl Into<Option<&'a str>>) -> &mut Self

Sets the name of the exported externrefs table where refs obtained from the host are placed. If set to None, the table will not be exported from the module.

By default, the table is exported as "externrefs".

pub fn set_drop_fn(&mut self, module: &'a str, name: &'a str) -> &mut Self

Sets a function to notify the host about dropped externrefs. This function will be added as an import with a signature (externref) -> () and will be called immediately before dropping each reference.

By default, there is no notifier hook installed.

pub fn process(&self, module: &mut Module) -> Result<(), Error>

Processes the provided module.

Errors

Returns an error if a module is malformed. This shouldn’t normally happen and could be caused by another post-processor or a bug in the externref crate / proc macro.

pub fn process_bytes(&self, bytes: &[u8]) -> Result<Vec<u8>, Error>

Processes the provided WASM module bytes. This is a higher-level alternative to Self::process().

Errors

Returns an error if bytes does not represent a valid WASM module, and in all cases Self::process() returns an error.

Trait Implementations

impl<'a> Debug for Processor<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Processor<'_>

fn default() -> Self

Returns the “default value” for a type.
