Struct SchedulingContext 

Source 
pub struct SchedulingContext { /* private fields */ }
👎Deprecated since 3.1.0: This crate has been marked for formal inclusion in the Agave Unstable API. From v4.0.0 onward, the agave-unstable-api crate feature must be specified to acknowledge use of an interface that may break without warning.
Expand description

A small context to propagate a bank and its scheduling mode to the scheduler subsystem.

Note that this isn’t called SchedulerContext because the contexts aren’t associated with schedulers one by one. A scheduler will use many SchedulingContexts during its lifetime. “Scheduling” part of the context name refers to an abstract slice of time to schedule and execute all transactions for a given bank for block verification or production. A context is expected to be used by a particular scheduler only for that duration of the time and to be disposed by the scheduler. Then, the scheduler may work on different banks with new SchedulingContexts.

There’s a special construction only used for scheduler preallocation, which has no bank. Panics will be triggered when tried to be used normally across code-base.
