Enum Reader 

pub enum Reader {
    Mem,
    Stream,
}

Strategy for reading SAS data into memory.

Clap’s ValueEnum derive converts PascalCase variants to lowercase for CLI input (e.g., Mem → mem).

Variants

Mem

Read all data into memory at once.

Stream

Stream data in chunks (default, lower memory usage).
