Struct ExtensionContext 

pub struct ExtensionContext {
    pub elapsed_ms: u64,
    pub consumed: u64,
    pub base: u64,
}

Snapshot of cursor state passed to an ExtensionPolicy at each end-reach decision point. Policies are pure predicates over this context — they don’t carry their own clocks or counters.

Fields

elapsed_ms: u64

Wall-clock milliseconds since the source factory was constructed (typically phase start).

consumed: u64

Global ordinals consumed so far — cursor.load() - start. Pass count is consumed / base.

base: u64

The base chunk size declared by the cursor. Used by policies that reason in passes rather than raw counts.

Implementations

impl ExtensionContext

pub fn passes(&self) -> u64

Convenience: integer pass count (consumed / base). Returns 0 when base == 0 (degenerate cursor).

Trait Implementations

impl Clone for ExtensionContext

fn clone(&self) -> ExtensionContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ExtensionContext

impl Debug for ExtensionContext

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

Formats the value using the given formatter.
