Struct PollerOptions 

pub struct PollerOptions {
    pub capacity: usize,
    pub overflow: PollerOverflow,
    pub block_timeout: Option<Duration>,
}

Options for Graph::add_poller_with_options.

Fields

capacity: usize

overflow: PollerOverflow

block_timeout: Option<Duration>

Block 溢出策略下，等宿主腾出一个槽位的上界。None 表示无上界， 仅适用于宿主确定会在另一个线程持续排水的场景。

Implementations

impl PollerOptions

pub fn new(capacity: usize, overflow: PollerOverflow) -> Self

Block 默认带 5 秒上界；有损策略下该字段无意义。

pub fn with_block_timeout(self, timeout: Option<Duration>) -> Self

覆盖 Block 的等待上界。
