eval_bits
Functions
expr_grp(Fields::[field()], Bindings::bindings(), EvalFun::evalfun(), ListOfBits::term(), X5::term()) -> {value, binary(), bindings()}
Returns a tuple with {value,Bin,Bs} where Bin is the binary constructed from form the Fields under the current Bindings. Bs contains the present bindings. This function can also throw an exception if the construction fails.
expr_grp(Fields, Bindings, EvalFun) -> term()
bin_gen(BinPattern::{bin, integer(), [field()]}, Bin::binary(), GlobalEnv::bindings(), LocalEnv::bindings(), MatchFun::matchfun(), EvalFun::evalfun()) -> {match, binary(), bindings()} | {nomatch, binary()} | done
Used to perform matching in a comprehension. If the match succeeds a new environment and what remains of the binary is returned. If the match fails what remains of the binary is returned. If nothing remains of the binary the atom 'done' is returned.
match_bits(Fields::[field()], Bin::binary(), GlobalEnv::bindings(), LocalEnv::bindings(), MatchFun::matchfun(), EvalFun::evalfun(), X7::term()) -> {match, bindings()}
Used to perform matching. If the match succeeds a new environment is returned. If the match have some syntactic or semantic problem which would have been caught at compile time this function throws 'invalid', if the matching fails for other reasons the function throws 'nomatch'
