Implementations§

source§

impl DynStructMut

source

pub fn from_parts( cfg: DynStructCfg, len: usize, validity: Option<BooleanBufferBuilder>, cols: Vec<DynColumnMut> ) -> Self

Create a DynStructMut from individual parts.

Note: it’s up to the user to ensure the provided cfg has the same column types as the provided cols. We can’t validate it here because DataTypes are not easily comparable.

source

pub fn len(&self) -> usize

Returns the number of elements in this column

source

pub fn cfg(&self) -> &DynStructCfg

Returns the configuration for this column.

source

pub fn as_mut(self) -> ColumnsMut

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

Panics if this struct is optional.

source

pub fn as_opt_mut(self) -> ColumnsMut<ValidityMut>

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.
