Implementations§

source§

impl DynStructCol

source

pub fn as_ref(&self) -> ColumnsRef

Explodes this non-optional struct column into its component fields.

Panics if this struct is optional.

source

pub fn as_opt_ref(&self) -> ColumnsRef<ValidityRef>

Explodes this optional struct column into its component fields and validity.

If the column is actually non-option, succeeds and acts as if every value is a Some.

source

pub fn from_arrow(cfg: DynStructCfg, array: &dyn Array) -> Result<Self, String>
