Trait QlogFilter 

pub trait QlogFilter:
    Send
    + Sync
    + 'static {
    // Required method
    fn matches(&self, event: &QlogEventView<'_>) -> bool;

    // Provided method
    fn generation(&self) -> u64 { ... }
}

Available on crate features quic and std only.

A cheap borrowed-event selection rule. Stateful filters advance generation whenever selection changes, so the connection can provide a fresh recovery snapshot.

Required Methods

fn matches(&self, event: &QlogEventView<'_>) -> bool

Return whether this borrowed observation should reach the wrapped sink.

Provided Methods

fn generation(&self) -> u64

Increment when selection changes to request a fresh recovery snapshot. Stable filters may keep the default.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
