source · pub struct OperatorsReader<'a> { /* private fields */ }
Expand description
A reader for a core WebAssembly function’s operators.
Implementations§
source§impl<'a> OperatorsReader<'a>
impl<'a> OperatorsReader<'a>
sourcepub fn original_position(&self) -> usize
pub fn original_position(&self) -> usize
Gets the original position of the reader.
sourcepub fn ensure_end(&self) -> Result<()>
pub fn ensure_end(&self) -> Result<()>
Ensures the reader is at the end.
This function returns an error if there is extra data after the operators.
sourcepub fn into_iter_with_offsets(self) -> OperatorsIteratorWithOffsets<'a> ⓘ
pub fn into_iter_with_offsets(self) -> OperatorsIteratorWithOffsets<'a> ⓘ
Converts to an iterator of operators paired with offsets.
sourcepub fn read_with_offset(&mut self) -> Result<(Operator<'a>, usize)>
pub fn read_with_offset(&mut self) -> Result<(Operator<'a>, usize)>
Reads an operator with its offset.
sourcepub fn visit_operator<T>(
&mut self,
visitor: &mut T,
) -> Result<<T as VisitOperator<'a>>::Output>where
T: VisitOperator<'a>,
pub fn visit_operator<T>(
&mut self,
visitor: &mut T,
) -> Result<<T as VisitOperator<'a>>::Output>where
T: VisitOperator<'a>,
Visit a single operator with the specified VisitOperator
instance.
See BinaryReader::visit_operator
for more information.
sourcepub fn get_binary_reader(&self) -> BinaryReader<'a>
pub fn get_binary_reader(&self) -> BinaryReader<'a>
Gets a binary reader from this operators reader.
sourcepub fn is_end_then_eof(&self) -> bool
pub fn is_end_then_eof(&self) -> bool
Returns whether there is an end
opcode followed by eof remaining in
this reader.

for body in code_reader {
let body = body.expect("function body");
let mut op_reader = body.get_operators_reader().expect("op reader");
let ops = op_reader.into_iter().collect::<Result<Vec<Operator>>>().expect("ops");
assert!(
if let [Operator::Nop, Operator::End] = ops.as_slice() { true } else { false },
"found {:?}",
ops
);
}
