Struct mz_persist_types::dyn_struct::DynStructMut

pub struct DynStructMut { /* private fields */ }

A crate::columnar::ColumnPush impl for DynStruct.

Implementations

impl DynStructMut

pub fn from_parts( cfg: DynStructCfg, len: usize, validity: Option<MutableBitmap>, 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.

pub fn len(&self) -> usize

Returns the number of elements in this column

pub fn cfg(&self) -> &DynStructCfg

Returns the configuration for this column.

pub fn as_mut(self) -> ColumnsMut

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

Panics if this struct is optional.

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.

Trait Implementations

impl ColumnPush<DynStruct> for DynStructMut

fn push<'a>(&mut self, val: DynStructRef<'a>)

Pushes a new value into this column.

impl ColumnPush<Option<DynStruct>> for DynStructMut

fn push<'a>(&mut self, val: Option<DynStructRef<'a>>)

Pushes a new value into this column.

impl Debug for DynStructMut

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<DynStructMut> for DynStructCol

fn from(value: DynStructMut) -> Self

Converts to this type from the input type.
