Struct ChannelSnapshot 

pub struct ChannelSnapshot { /* private fields */ }

Serializable userspace state of a Channel.

The Hub supplies the effective descriptor after fork/exec inheritance or explicit duplication. Only bytes that have not been consumed are captured; buffer offsets are normalized on restore while their capacities and backpressure state are preserved.

Implementations

impl ChannelSnapshot

pub fn has_buffered_input(&self) -> bool

Whether restoring this channel leaves input already available in userspace, independently of kernel readiness notifications.

pub fn has_buffered_output(&self) -> bool

Whether restoring this channel leaves output queued in userspace, independently of kernel readiness notifications.

pub fn buffered_bytes(&self) -> usize

Total userspace bytes that the kernel cannot report through readiness.
