Trait ColumnSource 

pub trait ColumnSource<T: Real> {
    // Required methods
    fn m(&self) -> usize;
    fn for_each_entry<F: FnMut(u32, T)>(&self, k: usize, f: F);
    fn nnz_hint(&self) -> usize;
    fn validate(&self) -> Result<(), SparseError>;
}

Where the factorization reads the columns of B from (the contract’s ColumnSource). Static dispatch only: crate::LuFactor::factorize is generic in the source, and ColumnSource::for_each_entry takes a generic visitor.

Required Methods

fn m(&self) -> usize

Order m of B (its number of columns).

fn for_each_entry<F: FnMut(u32, T)>(&self, k: usize, f: F)

Calls f(i, b_ik) for every stored entry of column k, rows increasing for structural columns.

fn nnz_hint(&self) -> usize

Upper bound on the nonzeros of B (an allocation hint).

fn validate(&self) -> Result<(), SparseError>

Checks that the source describes a square m × m matrix whose references are in range (invariant (B1)).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
