Struct BrowserRuntime 

pub struct BrowserRuntime { /* private fields */ }

Deterministic authority lifecycle and session clock.

This type is deliberately neither Clone nor Copy: duplicating it would fork the monotonic event clock for one session.

Implementations

impl BrowserRuntime

pub const fn new(session: RuntimeSessionId) -> Self

Start a fresh runtime session at generation one.

pub const fn snapshot(&self) -> RuntimeSnapshot

Read the complete immutable status.

pub const fn authority_state(&self) -> AuthorityState

Current authority state.

pub const fn ensure_policy_change_capacity(&self) -> Result<(), RuntimeError>

Whether policy revocation can advance both monotonic counters.

Errors

Returns RuntimeError::CounterExhausted if either counter is at its maximum value.

pub fn policy_changed(&mut self) -> Result<RuntimeSnapshot, RuntimeError>

Revoke prior work after a committed policy change.

Errors

Returns RuntimeError::CounterExhausted if the generation or event sequence cannot advance.

pub fn transition( &mut self, next: AuthorityState, ) -> Result<RuntimeSnapshot, RuntimeError>

Advance the exact browser authority state machine.

Errors

Returns RuntimeError::InvalidAuthorityTransition for an edge outside the required state graph, or RuntimeError::CounterExhausted if the event sequence cannot advance.

pub fn admit_event(&mut self) -> Result<RuntimeStamp, RuntimeError>

Record an admitted operation and bind it to this session/generation.

Errors

Returns RuntimeError::AuthorityNotReady before transport readiness, RuntimeError::Stopped after terminal shutdown, or RuntimeError::CounterExhausted if the event sequence cannot advance.

pub fn admits(&self, stamp: RuntimeStamp) -> bool

Check that a stamp belongs to current, already-admitted work.
