Struct node_testing::client::sc_executor::wasmi::Trap [−]
pub struct Trap { /* fields omitted */ }
Expand description
Error type which can be thrown by wasm code or by host environment.
Under some conditions, wasm execution may produce a Trap
, which immediately aborts execution.
Traps can’t be handled by WebAssembly code, but are reported to the embedder.

superset. Read more
pub fn is_in_subset(&self) -> bool
pub fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
pub fn to_subset_unchecked(&self) -> SS
pub fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
pub fn from_subset(element: &SS) -> SP
pub fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
The counterpart to unchecked_from
.
Consume self to return an equivalent value of T
.
