Implementations
sourceimpl<'a> GlobalSectionReader<'a>
impl<'a> GlobalSectionReader<'a>
sourcepub fn new(
data: &'a [u8],
offset: usize
) -> Result<GlobalSectionReader<'a>, BinaryReaderError>
pub fn new(
data: &'a [u8],
offset: usize
) -> Result<GlobalSectionReader<'a>, BinaryReaderError>
Constructs a new GlobalSectionReader
for the given data and offset.
sourcepub fn original_position(&self) -> usize
pub fn original_position(&self) -> usize
Gets the original position of the section reader.
sourcepub fn read<'b>(&mut self) -> Result<Global<'b>, BinaryReaderError> where
'a: 'b,
pub fn read<'b>(&mut self) -> Result<Global<'b>, BinaryReaderError> where
'a: 'b,
Reads content of the global section.
Examples
use wasmparser::GlobalSectionReader;
let mut global_reader = GlobalSectionReader::new(data, 0).unwrap();
for _ in 0..global_reader.get_count() {
let global = global_reader.read().expect("global");
println!("Global: {:?}", global);
let mut init_expr_reader = global.init_expr.get_binary_reader();
let op = init_expr_reader.read_operator().expect("op");
println!("Init const: {:?}", op);
}
