Struct ColumnCost 

pub struct ColumnCost {
    pub name: String,
    pub compressed_bytes: usize,
    pub share: f64,
}

Compressed cost of one encoded tile column.

Fields

name: String

Column name (e.g. geometry, start_time, a property name).

compressed_bytes: usize

Bytes when this column is IPC-encoded alone and zstd-compressed.

share: f64

Fraction of the summed per-column bytes in [0, 1]. Shares are of the per-column sum, which exceeds bytes_total (single-column re-encoding loses cross-column sharing and repays IPC framing per column).

Trait Implementations
