crates/blockifier/src/test_utils/cairo_compile.rs line 50 at r2 (raw file):

        DependencyValue::String(version) | DependencyValue::Object { version } => version.clone(),
    }
}

tested manually:

#[rstest]
fn test_manually() {
    assert_eq!("2.6.0", cairo1_compiler_version());
}

Code quote:

pub fn cairo1_compiler_version() -> String {
    let cargo_toml: CargoToml = toml::from_str(include_str!("../../../../Cargo.toml")).unwrap();
    match cargo_toml.workspace.dependencies.cairo_lang_casm {
        DependencyValue::String(version) | DependencyValue::Object { version } => version.clone(),
    }
}
