Struct wasm_bindgen_externref_xform::Context [−][src]
State of the externref pass, used to collect information while bindings are generated and used eventually to actually execute the entire pass.
Implementations
impl Context
[src]
pub fn prepare(&mut self, module: &mut Module) -> Result<(), Error>
[src]
Executed first very early over a wasm module, used to learn about how large the function table is so we know what indexes to hand out when we’re appending entries.
pub fn import_xform(
&mut self,
id: ImportId,
externref: &[(usize, bool)],
ret_externref: bool
) -> &mut Self
[src]
&mut self,
id: ImportId,
externref: &[(usize, bool)],
ret_externref: bool
) -> &mut Self
Store information about an imported function that needs to be
transformed. The actual transformation happens later during run
.
pub fn export_xform(
&mut self,
id: ExportId,
externref: &[(usize, bool)],
ret_externref: bool
) -> &mut Self
[src]
&mut self,
id: ExportId,
externref: &[(usize, bool)],
ret_externref: bool
) -> &mut Self
Store information about an exported function that needs to be
transformed. The actual transformation happens later during run
.
pub fn table_element_xform(
&mut self,
idx: u32,
externref: &[(usize, bool)],
ret_externref: bool
) -> Option<u32>
[src]
&mut self,
idx: u32,
externref: &[(usize, bool)],
ret_externref: bool
) -> Option<u32>
Store information about a function pointer that needs to be transformed.
The actual transformation happens later during run
. Returns an index
that the new wrapped function pointer will be injected at.
