//! Installing signal handlers allows us to handle traps and out-of-bounds memory
|
||||||
|
//! accesses that occur when runniing webassembly.
|
||||||
|
//!
|
||||||
|
//! This code is inspired by: https://github.com/pepyakin/wasmtime/commit/625a2b6c0815b21996e111da51b9664feb174622
|
||||||
|
//!
|
||||||
|
//! When a WebAssembly module triggers any traps, we perform recovery here.
|
||||||
|
//!
|
||||||
|
//! This module uses TLS (thread-local storage) to track recovery information. Since the four signals we're handling
|
||||||
|
//! are very special, the async signal unsafety of Rust's TLS implementation generally does not affect the correctness here
|
||||||
|
//! unless you have memory unsafety elsewhere in your code.
|
||||||
|
//!
