Implementations§

Source§

impl<'a> AnyValueBufferTrusted<'a>

Source

pub fn new(dtype: &DataType, len: usize) -> Self

Source

pub unsafe fn add_unchecked_owned_physical(&mut self, val: &AnyValue<'_>)

Will add the AnyValue into Self and unpack as the physical type belonging to Self. This should only be used with physical buffers

If a type is not primitive or String, the AnyValues will be converted to static

§Safety

The caller must ensure that the AnyValue type exactly matches the Buffer type and is owned.

Source

pub unsafe fn add_unchecked_borrowed_physical(&mut self, val: &AnyValue<'_>)

§Safety

The caller must ensure that the AnyValue type exactly matches the Buffer type and is borrowed.

Source

pub fn reset(&mut self, capacity: usize) -> Series

Clear self and give capacity, returning the old contents as a Series.

Source

pub fn into_series(self) -> Series
