Struct MailboxConfig 

pub struct MailboxConfig { /* private fields */ }

Memory + overflow contract for every mailbox spawned by a crate::Runtime.

Fields are private so an out-of-range capacity or byte budget cannot sneak in. Construct with MailboxConfig::new or MailboxConfig::DEFAULT, then narrow the byte budget with MailboxConfig::with_bytes.

Both bounds apply; the first one reached refuses the hop. See super::MailboxBytes for why the hop count alone is not a memory bound.

Implementations

impl MailboxConfig

pub const DEFAULT: MailboxConfig

Compile-time-valid default: 256 hops, 4 MiB, reject on overflow.

pub const fn new(capacity: MailboxCapacity, overflow: OverflowPolicy) -> Self

Capacity + policy, with the default byte budget.

The byte budget is a separate builder step rather than a third parameter so embedders that only care about hop count are not forced to reason about bytes to keep compiling.

pub const fn with_bytes(self, bytes: MailboxBytes) -> Self

Replace the byte budget.

pub const fn capacity(&self) -> MailboxCapacity

pub const fn bytes(&self) -> MailboxBytes

pub const fn overflow(&self) -> OverflowPolicy
