Enum LinearizerError 

pub enum LinearizerError {
    SymbolicStructure(String),
    ParallelComputation(String),
    Variable(String),
    FactorLinearization(String),
    InvalidInput(String),
}

Linearizer-specific error types for Jacobian assembly and symbolic structure operations.

These errors occur during the linearization phase of optimization, where the nonlinear factor graph is converted into a linear system (residual vector and Jacobian matrix).

Error Hierarchy

LinearizerError is a Layer C (deep/module) error. It propagates up through:

• CoreError::Linearizer(LinearizerError) → for core module callers
• ApexSolverError::Linearizer(LinearizerError) → for direct API callers

Variants

SymbolicStructure(String)

Symbolic structure construction or usage failed

ParallelComputation(String)

Parallel computation error (thread/mutex failures during assembly)

Variable(String)

Variable key missing in index mapping during Jacobian scatter

FactorLinearization(String)

Factor linearization returned no Jacobian when expected

InvalidInput(String)

Invalid input (e.g., SparseMode requires symbolic structure)

Trait Implementations

impl Clone for LinearizerError

fn clone(&self) -> LinearizerError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LinearizerError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for LinearizerError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

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
