Possible workaround: try enabling rsfbclient
feature date_time
explicitly in your build command or Cargo.toml
(if you need help doing this, please say so)
It became essentially non-optional at some point and the breakage was never dealt with.
Please say if this works, so that this issue may be closed if so. I have opened a separate issue for the underlying problem i described, at #103
What am I doing wrong?
Maybe you are turning off the default features
. I think the @dancingbug workaround will work.
Waiting your feedback.
Yes, the tip from @dancinbug did solve the missing data_time feature issue, so thank you very much for that one. It is probably because I'm quite new to Rust that I'm running into some new issues.
Because I would like to try the pure rust option I now have this in Cargo.toml: rsfbclient = {version = "0.15.0", default-features = false, features = ["pure_rust", "date_time"]}
And a function, according to the string_conn.rs example from the Github repo, like this: fn wisatest() -> Result<(), rsfbclient::FbError> {
#[cfg(feature = "pure_rust")]
let mut conn = rsfbclient::builder_pure_rust()
.from_string("firebird://SYSDBA:<mypassword>@<myhost>:3050/home/firebird/data/CVODEVERDIEPING.fb?charset=win1252")?
.connect()?
.into();
let rows = conn.query_iter("SELECT FIRST 10 LL_VOORNAAM,LL_NAAM FROM LEERLING",())?;
for row in rows {
let (voornaam,naam,) : (String,String,) = row;
println!("{} {}",voornaam,naam);
};
Ok(())
}
When I now build the project I get this:
Compiling rsfbclient-native v0.15.0
Compiling rsfbclient v0.15.0
Compiling guessing_game v0.1.0 (/opt/rust/guessing_game)
error[E0425]: cannot find value conn

51 | let rows = conn.query_iter("SELECT FIRST 10 LL_VOORNAAM,LL_NAAM FROM LEERLING",())?;
| ^^^^ not found in this scope
error: aborting due to previous error
I don't understand why conn is not in scope since it is declared and defined one statement earlier? The strange thing also is that the last few dependencies are also always recompiled?
Again, maybe this is due to the fact I'm new to Rust, so don't feel obliged in any way to solve this for me if I should be able to figure it out by myself. Help is however very much appreciated :-)

You are using the #[cfg(feature = "pure_rust")]
. Remove it. This is not used on this context.
Closing this issue as the original problem as stated was resolved.
I am fairly certain removing the cfg
guard like @fernandobatels suggested will resolve your other error.
@hermanius if you continue to run into new problems, feel free to open new issues as needed.
After adding rsfbclient-rust = "0.15.0" to Cargo.toml and building I get the following error during the build:
