Example
```
use wasmparser::Parser;
use wasmparser::ParserState;
fn getname(bytes: &[u8]) -> &str {
str::fromutf8(bytes).ok().unwrap()
}
fn main() {
let ref buf: Vec = readwasm().unwrap();
let mut parser = Parser::new(buf);
loop {
let state = parser.read();
if state.isnone() {
break;
}
match state.unwrap() {
ParserState::BeginWasm { .. } => {
println!("====== Module");
}
ParserState::ExportSectionEntry { field, ref kind, .. } => {
println!(" Export {} {:?}", get_name(field), kind);
}
ParserState::ImportSectionEntry { module, field, .. } => {
println!(" Import {}::{}", get_name(module), get_name(field))
}
_ => ( / println!(" Other {:?}", state); */ )
}
}
}
