Struct VectorWriter

Source
pub struct VectorWriter<'a, 'b, A: ScalarAtom> { /* private fields */ }
Expand description

Handle to append elements to a vector.

This works by allocating a slice of memory behind the vector and then writing your data to it.

Implementations§

Source§

impl<'a, 'b, A: ScalarAtom> VectorWriter<'a, 'b, A>

Source

pub fn push(&mut self, child: A::InternalType) -> Option<&mut A::InternalType>

Push a single value to the vector.

Source

pub fn allocate(&mut self, size: usize) -> Option<&mut [A::InternalType]>

Append a slice of undefined memory to the vector.

Using this method, you don’t need to have the elements in memory before you can write them.

Source

pub fn append( &mut self, data: &[A::InternalType], ) -> Option<&mut [A::InternalType]>

Append multiple elements to the vector.
