Struct ValueBatchMut 

pub struct ValueBatchMut<'a> {
    pub n_rows: usize,
    pub n_nodes: usize,
    pub values: &'a mut [f64],
}

Mutable view into a value batch (owned buffer).

Fields

n_rows: usize

Rows.

n_nodes: usize

Nodes.

values: &'a mut [f64]

Flat column-major storage.

Implementations

impl<'a> ValueBatchMut<'a>

pub fn new( n_rows: usize, n_nodes: usize, values: &'a mut [f64], ) -> Result<Self, ModelError>

Wrap a buffer.

Errors

Length mismatch.

pub fn column_mut(&mut self, node: usize) -> Result<&mut [f64], ModelError>

Mutable column slice.

Errors

Out of range.

pub fn set(&mut self, row: usize, node: usize, v: f64) -> Result<(), ModelError>

Set (row, node).

Errors

Out of range.

pub fn into_batch(self) -> ValueBatch

Freeze into an owned ValueBatch.
