Module logging

Substrate logging library.

This crate uses tokio’s tracing library for logging.

Structs

• EventFormat
  A pre-configured event formatter.
• FastLocalTime
  A structure which, when Displayd, will print out the current local time.
• LoggerBuilder
  A builder that is used to initialize the global logger.
• PrefixLayer
  A Layer that captures the prefix span (PREFIX_LOG_SPAN) which is then used by crate::logging::EventFormat to prefix the log lines by customizable string.

Enums

• Error
  Logging errors.

Constants

• PREFIX_LOG_SPAN
  Span name used for the logging prefix. See macro sc_tracing::logging::prefix_logs_with!

Functions

• add_directives
  Add directives to current directives.
• get_directives
  Returns the current directives.
• reload_filter
  Reload the logging filter with the supplied directives added to the existing directives
• reset_log_filter
  Resets the log filter back to the original state when the node was started.

Type Aliases

• Result
  Logging Result typedef.

Attribute Macros

• prefix_logs_with
  This prefixes all the log lines with [<name>] (after the timestamp). It works by making a tracing’s span that is propagated to all the child calls and child tasks (futures) if they are spawned properly with the SpawnHandle (see TaskManager in sc-cli) or if the futures use .in_current_span() (see tracing-futures).
