Struct EventMetadata 

pub struct EventMetadata {
    pub level: String,
    pub message: String,
    pub target: String,
    pub fields: BTreeMap<Cow<'static, str>, Cow<'static, str>>,
}

Metadata about a log event for human-readable summaries.

Stores the essential details needed to understand what event was suppressed without having to correlate the signature hash with the original log.

Uses Cow<'static, str> to reduce allocations when possible, particularly for field names which are often static in tracing macros.

Fields

level: String

Log level (e.g., “INFO”, “WARN”, “ERROR”)

message: String

Message template

target: String

Target module path

fields: BTreeMap<Cow<'static, str>, Cow<'static, str>>

Structured fields (key-value pairs)

Implementations

impl EventMetadata

pub fn new( level: String, message: String, target: String, fields: BTreeMap<Cow<'static, str>, Cow<'static, str>>, ) -> Self

Create new event metadata.

pub fn format_brief(&self) -> String

Format a brief description of the event for display.

Returns a string like: [ERROR] database::connection: Connection failed

pub fn format_detailed(&self) -> String

Format the event with fields for detailed display.

Returns a string like: [ERROR] database::connection: Connection failed {error_code="TIMEOUT", retry_count="3"}

Trait Implementations

impl Clone for EventMetadata

fn clone(&self) -> EventMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventMetadata

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

Formats the value using the given formatter.

impl PartialEq for EventMetadata

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