Struct ColumnsSpec 

pub struct ColumnsSpec {
    pub from: String,
    pub header: Option<String>,
    pub header_label: Option<String>,
    pub value: String,
}

Available on crate feature transform-tree-flatten only.

How the value columns are read from a leaf node.

Fields

from: String

Path (within a node) to the leaf’s cell array — e.g. ColData.

header: Option<String>

Path (within the whole record) to the header definitions, paired positionally with the cells to name the value columns. Absent → cells are named col_0, col_1, ….

header_label: Option<String>

Field within each header element holding its label (e.g. ColTitle). Absent → the header element is used as a scalar string.

value: String

Field within each cell holding the value (e.g. value). Absent-in-cell → the whole cell is used.
