GLIBC incompatibility on debian docker

I’m trying to build a rust app with rust-rocksdb as a dependency.

Using the latest rust docker image to compile and then moving the binary to a debian.
This is how my Dockerfile looks

FROM rust:1.61 as builder

RUN USER=root cargo new --bin fbrust
WORKDIR ./fbrust
COPY ./Cargo.toml ./Cargo.toml
COPY ./Cargo.lock ./Cargo.lock

RUN apt-get update 
    && apt-get install -y ca-certificates tzdata libclang-dev 
    && rm -rf /var/lib/apt/lists/*

RUN cargo build --release
RUN rm src/*.rs

ADD . ./

RUN rm ./target/release/deps/fbrust*
RUN cargo build --release


FROM debian:buster-slim
ARG APP=/usr/src/app

EXPOSE 5005

ENV TZ=Etc/UTC 
APP_USER=appuser

RUN groupadd $APP_USER 
    && useradd -g $APP_USER $APP_USER 
    && mkdir -p ${APP}

COPY --from=builder /fbrust/target/release/fbrust ${APP}/fbrust

RUN chown -R $APP_USER:$APP_USER ${APP}

USER $APP_USER
WORKDIR ${APP}

CMD ["./fbrust"]

I’m now getting this error(s):

./fbrust: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by ./fbrust)
./fbrust: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.30' not found (required by ./fbrust)
./fbrust: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by ./fbrust)

First of all, I’m confused why do I see both 2.29 and 2.30 required.

I checked within the container and indeed I have 2.28

||/ Name           Version      Architecture Description
+++-==============-============-============-=================================
ii  libc-bin       2.28-10      amd64        GNU C Library: Binaries

Is there any other image I can use to achieve compatibility or can I get a hint on what dependencies/setup should I try?
