Struct Builder 

pub struct Builder<'a, T>
where
    T: PrimitiveElement,
{ /* private fields */ }

Implementations

impl<'a, T> Builder<'a, T>

where T: PrimitiveElement,

pub fn len(&self) -> u32

pub fn is_empty(&self) -> bool

pub fn into_reader(self) -> Reader<'a, T>

pub fn set(&mut self, index: u32, value: T)

pub fn as_slice(&mut self) -> Option<&mut [T]>

Attempts to return a view of the list as a native Rust slice.

Returns None if either:

• The elements of the list are non-contiguous, which can happen if the schema has evolved.
• The elements of the list are bit-sized, i.e. T is bool. In the case, the list is bit-packed, and therefore differs in representation from Rust’s &[bool].

This method raises a compile-time error if T is larger than one byte and either the unaligned feature is enabled or the target is big-endian.

impl<T: PrimitiveElement> Builder<'_, T>

pub fn get(&self, index: u32) -> T

Gets the T at position index. Panics if index is greater than or equal to len().

pub fn try_get(&self, index: u32) -> Option<T>

Gets the T at position index. Returns None if index is greater than or equal to len().

pub fn reborrow(&mut self) -> Builder<'_, T>
