Struct wasmprinter::Printer
source · pub struct Printer { /* private fields */ }
Expand description
Context used for printing a WebAssembly binary.
This is largely only required if you’d like to register custom printers for custom sections in a wasm binary.
Implementations§
source§impl Printer
impl Printer
sourcepub fn new() -> Self
pub fn new() -> Self
Creates a new Printer
object that’s ready to start printing wasm
binaries to strings.
sourcepub fn print_offsets(&mut self, print: bool)
pub fn print_offsets(&mut self, print: bool)
Whether or not to print binary offsets of each item as comments in the text format whenever a newline is printed.
sourcepub fn add_custom_section_printer(
&mut self,
section: &str,
printer: impl FnMut(&mut Printer, usize, &[u8]) -> Result<()> + 'static
)
pub fn add_custom_section_printer( &mut self, section: &str, printer: impl FnMut(&mut Printer, usize, &[u8]) -> Result<()> + 'static )
Registers a custom printer
function to get invoked whenever a custom
section of name section
is seen.
This can be used to register printers into a textual format for custom sections, such as by emitting annotations and/or other textual references (maybe comments!)
By default all custom sections are ignored for the text format.
The printer
function provided takes three arguments:
- A
&mut Printer
, or where to print results to - A
usize
offset which is the start of the offset for the custom section - A byte slice which is the actual contents of the custom section.
sourcepub fn result_mut(&mut self) -> &mut String
pub fn result_mut(&mut self) -> &mut String
Gets the output result of this Printer
, or where all output is going.
