Struct LogContext 

pub struct LogContext { /* private fields */ }

A set of records that can be attached to a logging scope.

LogContext represents a set of key-value pairs that will be automatically added to log messages when the context scope is active.

Implementations

impl LogContext

pub const fn new() -> Self

Creates a new, empty context.

pub fn with_record( self, key: impl Into<Cow<'static, str>>, value: impl Into<LogValue>, ) -> Self

Adds a record to this context.

Ordering

The order in which records appear in log output is not guaranteed. Do not rely on any specific ordering of keys.

Examples

use context_logger::LogContext;

let context = LogContext::new()
    .with_record("user_id", "user-123")
    .with_record("request_id", 42)
    .with_record("is_admin", true);
