Struct wasmer_compiler::MiddlewareBinaryReader

pub struct MiddlewareBinaryReader<'a> {
    state: MiddlewareReaderState<'a>,
    chain: Vec<Box<dyn FunctionMiddleware>>,
}

A Middleware binary reader of the WebAssembly structures and types.

Fields

state: MiddlewareReaderState<'a>

Parsing state.

chain: Vec<Box<dyn FunctionMiddleware>>

The backing middleware chain for this reader.

Implementations

impl<'a> MiddlewareBinaryReader<'a>

pub fn new_with_offset(data: &'a [u8], original_offset: usize) -> Self

Constructs a MiddlewareBinaryReader with an explicit starting offset.

pub fn set_middleware_chain(&mut self, stages: Vec<Box<dyn FunctionMiddleware>>)

Replaces the middleware chain with a new one.
