Macros

  • alert
    Convenience macro for the alert function.
  • async_enter
    Convenience macro for the async_enter function, which can be used to trace the duration of a scope containing async code. This macro returns the drop guard, which the caller may then choose to manage.
  • async_instant
    Convenience macro for the async_instant function, which can be used to emit an async instant event.
  • blob
  • counter
    Convenience macro for the counter function.
  • cstr
    Creates a &'static CStr from a string literal.
  • duration
    Convenience macro for the duration function that can be used to trace the duration of a scope. If you need finer grained control over when a duration starts and stops, see duration_begin and duration_end.
  • duration_begin
    Convenience macro for the duration_begin function.
  • duration_end
    Convenience macro for the duration_end function.
  • flow_begin
    Convenience macro for the flow_begin function.
  • flow_end
    Convenience macro for the flow_end function.
  • flow_step
    Convenience macro for the flow_step function.
  • instant
    Convenience macro for the instant function.
  • string_name_macro
    Creates a convenience macro that returns a string literal.

Structs

  • Arg
    Arg holds an argument to a tracing function, which can be one of many types.
  • AsyncScope
    AsyncScope maintains state around the context of async events generated via the async_enter! macro.
  • Context
    RAII wrapper for trace contexts without a specific associated category.
  • DurationScope
    The scope of a duration event, returned by the duration function and the duration! macro. The duration will be end'ed when this object is dropped.
  • Id
    An identifier for flows and async spans.
  • ProlongedContext
  • TraceCategoryContext
    RAII wrapper for a trace context for a specific category.

Enums

Constants

Traits

  • ArgValue
    A trait for types that can be the values of an argument set.

Functions

  • alert
    Sends an alert, which can be mapped to an action.
  • async_begin
    Writes an async begin event. This event must be matched by an async end event with the same id, category, and name. This function is intended to be called through use of the async_enter! macro.
  • async_end
    Writes an async end event. This event must be associated with a prior async begin event with the same id, category, and name. This function is intended to be called implicitly when the AsyncScope object created through use of the async_enter! macro is dropped.
  • async_enter
    Writes an async event which ends when the current scope exits, or the end method is is manually called.
  • async_instant
    Writes an async instant event with the specified id.
  • blob_fn
  • category_enabled
    Returns true if tracing has been enabled for the given category.
  • complete_duration
    Write a “duration complete” record representing both the beginning and end of a duration.
  • counter
    Writes a counter event with the specified id.
  • duration
    Writes a duration event which ends when the current scope exits, or the end method is manually called.
  • duration_begin
    Writes a duration begin event only. This event must be matched by a duration end event with the same category and name.
  • duration_end
    Writes a duration end event only.
  • flow_begin
    Writes a flow begin event with the specified id. This event may be followed by flow steps events and must be matched by a flow end event with the same category, name, and id.
  • flow_end
    Writes a flow end event with the specified id.
  • flow_step
    Writes a flow step event with the specified id.
  • instant
    Writes an instant event representing a single moment in time. The number of args must not be greater than 15.
  • is_enabled
    Returns true if tracing is enabled.
  • trace_state
