Struct wasmtime::WasmCoreDump
source · pub struct WasmCoreDump { /* private fields */ }
Expand description
Representation of a core dump of a WebAssembly module
When the Config::coredump_on_trap option is enabled this structure is
attached to the anyhow::Error
returned from many Wasmtime functions that
execute WebAssembly such as Instance::new
or Func::call
. This can be
acquired with the anyhow::Error::downcast
family of methods to
programmatically inspect the coredump. Otherwise since it’s part of the
error returned this will get printed along with the rest of the error when
the error is logged.
Note that some state, such as Wasm locals or values on the operand stack, may be optimized away by the compiler or otherwise not recovered in the coredump.
Capturing of wasm coredumps can be configured through the
Config::coredump_on_trap
method.
For more information about errors in wasmtime see the documentation of the
Trap
type.
