ld: region `drom0_0_seg' overflowed

Hello,
My codes have worked until more and more codes are developed. When I run "cargo build", it throws the following errors
= note: [ldproxy] Running ldproxy Error: Linker /home/<my_home>/.espressif/tools/riscv32-esp-elf/esp-2022r1-11.2.0/riscv32-esp-elf/bin/riscv32-esp-elf-gcc failed: exit status: 1 STDERR OUTPUT: /home/<my_home>/.espressif/tools/riscv32-esp-elf/esp-2022r1-11.2.0/riscv32-esp-elf/bin/../lib/gcc/riscv32-esp-elf/11.2.0/../../../../riscv32-esp-elf/bin/ld: /drn/RustProjects/pomodoro/target/riscv32imc-esp-espidf/debug/deps/Pomodoro-1b9aac50edb587b3 section ".flash.rodata" will not fit in region "drom0_0_seg" /home/<my_home>/.espressif/tools/riscv32-esp-elf/esp-2022r1-11.2.0/riscv32-esp-elf/bin/../lib/gcc/riscv32-esp-elf/11.2.0/../../../../riscv32-esp-elf/bin/ld: region "drom0_0_seg" overflowed by 380184 bytes collect2: error: ld returned 1 exit status
here is my env:
- Ubuntu 22
- ESP-IDF 5.0
- MCU: ESP32 C3
I found some solutions for it, but they are all for Arduino and C language, not rust, how to fix it?
Your help would be greatly appreciated!
Your application is too big to fit into ROM (flash). Make sure you're building with --release flag and/or look into reducing the size of your application.
@MabezDev Thanks a lot, --release flag works, I am concerned that even this flag may not be sustainable for longer periods of time as more features are developed.
Binary size management is something you will have to consider in any language. You could always buy a chip that has more flash, of course.
Closing this for now, if you have some specific size optimization questions feel free to open another issue
