# Backend internal interview (rust) - improved
|
|
|
|
## How to used
|
|
|
|
**cargo run --** can be replaced for generated binaries with
|
|
|
|
- target/debug/be-technical-interview-rust (for debug build)
|
|
- target/release/be-technical-interview-rust (for release build)
|
|
|
|
### For help
|
|
|
|
```bash
|
|
cargo run -- -h
|
|
```
|
|
|
|
### For input file **input.txt**
|
|
|
|
```bash
|
|
cargo run -- -i input.txt
|
|
```
|
|
|
|
### In quiet mode
|
|
|
|
```bash
|
|
cargo run -- -i input.txt -q
|
|
```
|
|
|
|
if **output path** is provided, results will be saved in provided path,<br>
|
|
without **quiet mode** info is printed to terminal
|
|
|
|
```bash
|
|
cargo run -- -i input.txt -o /tmp/output.txt
|
|
```
|
|
|
|
### Use config path. **Batch processing in parallel** (one thread for each target)
|
|
|
|
```bash
|
|
cargo run -- -c config.toml
|
|
```
|
|
|
|
### Config file content
|
|
|
|
```toml
|
|
be_quiet = false
|
|
[[targets]]
|
|
input = "input.txt"
|
|
|
|
[[targets]]
|
|
input = "input_2.txt"
|
|
```
|
|
|
|
If **output** path is provided, **out_overwrite** can be used (true or false) to append conten or rewrite.
|
|
|
|
By default:
|
|
|
|
- **out_overwrite** is **true**
|
|
- *reg_exp** is set as
|
|
|
|
```rust
|
|
pub const DEFAULT_REG_EXP: &str = r"(\d+) (\w+) (\d+)";
|
|
```
|
|
|
|
**reg_exp** can be provided but as a **regex** expresion from **string**, if it can not be converted parser exit.
|
|
|
|
To solve this
|
|
|
|
```toml
|
|
be_quiet = false
|
|
[[targets]]
|
|
input = "input.txt"
|
|
# \ has to be escaped
|
|
reg_exp = "(\\d+) (\\w+) (\\d+)"
|
|
|
|
[[targets]]
|
|
input = "input_2.txt"
|
|
```
|
|
|
|
> [!CAUTION]
|
|
> Command line options have precedence over **config path** settings. <br>
|
|
> Be careful with the combinations
