Struct InMemorySink 

pub struct InMemorySink { /* private fields */ }

A reference / test sink that retains up to MAX_RETAINED_SPANS spans in memory.

Implementations

impl InMemorySink

pub fn new() -> Self

pub fn spans(&self) -> Vec<FilterSpan>

A snapshot of every span captured so far.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl Debug for InMemorySink

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

Formats the value using the given formatter.

impl Default for InMemorySink

fn default() -> InMemorySink

Returns the “default value” for a type.

impl TelemetrySink for InMemorySink

fn export(&self, span: &FilterSpan)

fn enabled(&self) -> bool

Whether this sink consumes spans at all. When false, the host skips span construction entirely on the per-request path — build_filter_span allocates (name, attributes, one event per host-log line), which would otherwise be paid per hook call just to be dropped by export. Defaults to true; only a sink that discards everything should override.
