§evaluated_models: u16

How many models were evaluated.

§eligible_models: u16

Implementations§

impl KernelDecision

pub const fn is_executable(&self) -> bool

Returns true when the decision selected a model that may be executed.

pub const fn is_requested_execution(&self) -> bool

Returns true when the requested model was selected.

pub const fn is_substitution(&self) -> bool

Returns true when a different eligible model was selected.

pub const fn is_rejected(&self) -> bool

Returns true when the request failed closed and no model was selected.
