Struct LogQuery 

pub struct LogQuery {
    pub service: Option<ServiceName>,
    pub levels: Vec<Level>,
    pub target: Option<TargetCategory>,
    pub action: Option<ActionName>,
    pub request_id: Option<CorrelationId>,
    pub correlation_id: Option<CorrelationId>,

    pub until: Option<Timestamp>,
    pub field_matches: Vec<LogFieldMatch>,
    pub limit: Option<usize>,
    pub order: LogOrder,
}

Shared historical/follow query contract used by the logging reader/runtime layers.

Fields

service: Option<ServiceName>

Optional service filter.

levels: Vec<Level>

Allowed severity levels; empty means any level.

target: Option<TargetCategory>

Optional target/category filter.

action: Option<ActionName>

Optional action filter.

request_id: Option<CorrelationId>

Optional request identifier filter.

correlation_id: Option<CorrelationId>

Optional correlation identifier filter.

since: Option<Timestamp>

Optional inclusive lower timestamp bound.

until: Option<Timestamp>

Optional inclusive upper timestamp bound.

field_matches: Vec<LogFieldMatch>

Exact-match field predicates.

limit: Option<usize>

Optional maximum number of returned events.

order: LogOrder

Result ordering.

Implementations

impl LogQuery

pub fn validate(&self) -> Result<(), QueryError>

Validates the frozen shared query semantics before runtime execution.

Errors

Returns QueryError::InvalidQuery when the query violates the shared contract for limit or timestamp-range semantics.

Trait Implementations

impl Clone for LogQuery

fn clone(&self) -> LogQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogQuery

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

Formats the value using the given formatter.

impl Default for LogQuery

fn default() -> LogQuery

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LogQuery

fn deserialize<__D>( __deserializer: __D, ) -> Result<LogQuery, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LogQuery

fn eq(&self, other: &LogQuery) -> 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.

impl Serialize for LogQuery

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
