Struct InitialPeek 

pub struct InitialPeek<H, P> { /* private fields */ }

Available on crate features quic and std only.

Incremental, opt-in ClientHello inspection for one QUIC connection attempt.

Each datagram is decrypted once, with the attempt’s Initial keys derived once. Retransmissions, frames, fragments and input bytes consume cumulative budgets. The deadline is absolute and never renewed. Both successful completion and errors release retained Initials and prevent reuse. Callers must also expire a pending inspector when no datagrams arrive. This type deliberately has no raw-data Debug or serialization implementation.

Implementations

impl<H, P> InitialPeek<H, P>

where H: HeaderKey, P: PacketKey,

pub fn new(limits: CaptureLimits, deadline: Instant) -> InitialPeek<H, P>

pub fn new_with_first_flight( limits: CaptureLimits, deadline: Instant, ) -> InitialPeek<H, P>

Inspect with bounded structural retention, without keeping another ClientHello copy. The result describes only the prefix through the datagram completing ClientHello.

pub fn deadline(&self) -> Instant

Absolute deadline the caller uses for its receive timeout.

pub fn inspect<K>( &mut self, now: Instant, datagram: &[u8], provider: &K, ) -> Result<Option<PeekedClientHello>, PeekError>

where K: KeyProvider<Header = H, Packet = P>,

Inspect one logical UDP datagram. None means more CRYPTO bytes are needed. Neither this call nor its key provider may emit QUIC responses.
