Expand description
TrSelector
implementors are used to select a random transition given an Fst
state s
, returning a number N
such that 0 <= N
<= fst.num_trs(s)
. If N
is
fst.num_trs(s)
, then the final weight is selected; otherwise the N
-th transition is
selected. It is assumed these are not applied to any state which is neither
final nor has any arcs leaving it.

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
