Struct RootBatchFailure 

pub struct RootBatchFailure {
    pub total: usize,
    pub failure_count: usize,
    pub first_index: usize,
    pub first_status: RootStatus,
    pub first_iterations: u32,
}

One or more lanes of a RootBatch did not converge.

Returned by RootBatch::roots. It names both the scale of the problem (how many of how many) and a specific lane to look at, because “3 of 10 000 cells failed” is only actionable once you know which cell.

Units

All counts and indices are dimensionless.

Fields

total: usize

Number of lanes in the batch.

failure_count: usize

Number of lanes that did not converge.

first_index: usize

Index of the first non-converged lane.

first_status: RootStatus

Why that lane failed.

first_iterations: u32

Iterations that lane performed before giving up.

impl Eq for RootBatchFailure

impl Error for RootBatchFailure

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
