Enum TailVisibility 

#[non_exhaustive]
pub enum TailVisibility {
    All,
    ExcludeBestEffort,
}

Tail-stream visibility filter (RFC-015 §6).

Default Self::All preserves v1 behaviour; opt-in Self::ExcludeBestEffort filters out BestEffortLive frames on the server side (the XADD mode field is a cheap field check in ff_read_attempt_stream / xread_block).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

All

Default. Returns every XADD entry in the stream regardless of mode.

ExcludeBestEffort

Returns only frames appended under StreamMode::Durable or StreamMode::DurableSummary (i.e. filters out StreamMode::BestEffortLive). Named to be self-describing: the filter excludes best-effort frames, not “only Durable” — DurableSummary deltas are included because they have a durable backing (the summary Hash).

Implementations

impl TailVisibility

pub fn wire_str(&self) -> &'static str

Stable wire-level token pushed as an ARGV to the Lua tail/read implementations. "" (empty) means default = All (no filter).

Trait Implementations

impl Clone for TailVisibility

fn clone(&self) -> TailVisibility

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TailVisibility

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for TailVisibility

fn default() -> TailVisibility

Returns the “default value” for a type.

impl Hash for TailVisibility

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TailVisibility

fn eq(&self, other: &TailVisibility) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
