Implementations
sourceimpl Target
impl Target
sourcepub fn from_column(name: &str) -> ColumnTarget
pub fn from_column(name: &str) -> ColumnTarget
Write output to a file whose path is specified by the given column.
This gives the oportunity to create a stream that writes to multiple files depending on some criteria. It doesn’t write the value of the specified column by default, it is just used to decide the path to the file(s) for writing but that behaviour is configurable.
