Delbin

Descriptive Language for Binary Object

Delbin is a Domain Specific Language (DSL) and its supporting library for describing and generating binary data structures, primarily used for Header information generation in embedded firmware packaging scenarios.

Example

use delbin::{generate, Value};
use std::collections::HashMap;

let dsl = r#"
    @endian = little;
    struct header @packed {
        magic: [u8; 4] = @bytes("FPK\0");
        version: u32 = ${VERSION};
        size: u32 = @sizeof(image);
    }
"#;

let mut env = HashMap::new();
env.insert("VERSION".to_string(), Value::U64(0x0100));

let mut sections = HashMap::new();
sections.insert("image".to_string(), vec![0u8; 1024]);

let result = generate(dsl, &env, &sections).unwrap();
assert_eq!(result.data.len(), 12); // 4 + 4 + 4
