Implementations
sourceimpl<'a> MemorySectionReader<'a>
impl<'a> MemorySectionReader<'a>
sourcepub fn new(
data: &'a [u8],
offset: usize
) -> Result<MemorySectionReader<'a>, BinaryReaderError>
pub fn new(
data: &'a [u8],
offset: usize
) -> Result<MemorySectionReader<'a>, BinaryReaderError>
Constructs a new MemorySectionReader
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(&mut self) -> Result<MemoryType, BinaryReaderError>
pub fn read(&mut self) -> Result<MemoryType, BinaryReaderError>
Reads content of the memory section.
Examples
use wasmparser::MemorySectionReader;
let mut memory_reader = MemorySectionReader::new(data, 0).unwrap();
for _ in 0..memory_reader.get_count() {
let memory = memory_reader.read().expect("memory");
println!("Memory: {:?}", memory);
}
