Struct DatasetWriteOptions 

pub struct DatasetWriteOptions {
    pub batch_size: usize,
    pub precision: FloatPrecision,
    pub tree: Option<String>,
}

Options for writing a Dataset to disk.

Fields

batch_size: usize

Number of events to include in each batch when writing.

precision: FloatPrecision

Floating-point precision to use for persisted columns.

tree: Option<String>

Tree name to use when writing ROOT files.
