Struct Layout 

pub struct Layout {
    pub frames: Vec<u32>,
    pub pos_of: HashMap<String, usize>,
}

위치 ↔ 영상 이름. 위치 = 선택된 프레임 목록의 순번(파일 번호 / stride 가 아님).

Fields

frames: Vec<u32>

위치별 입력 파일의 프레임 번호.

pos_of: HashMap<String, usize>

영상 이름 → 위치.

Implementations

impl Layout

pub fn discover(src: &Path, stride: usize) -> Result<Self, String>

images/camF/camF_NNNN.jpg 중 번호 % stride == 0 인 것(번호 오름차순).
