Struct ScanOptions 

pub struct ScanOptions {
    pub pattern: String,
    pub batch_size: usize,
    pub count_hint: usize,
    pub n_rows: Option<usize>,
    pub parallel: ParallelStrategy,
}

Common scan options shared across all Redis data types.

Fields

batch_size: usize

Number of keys to process per batch.

count_hint: usize

SCAN COUNT hint for Redis.

n_rows: Option<usize>

Maximum total rows to return (None for unlimited).

parallel: ParallelStrategy

Parallel processing strategy.
