Module quicklog::level

contains logging levels and filters Defines the levels of verbosity available for logging, as well as LevelFilter.

Logging Levels

Defined in Level. Consists of 5 levels in total:

• Trace
• Debug
• Info
• Warn
• Error

LevelFilters

Similarly, LevelFilter correspond to [Level'], with the addition of [LevelFilter::Off`].

Logging levels will be skipped if a level is lower than current LevelFilter, i.e. Level::Debug is skipped when LevelFilter is set to Info, but Level::Info logs will not be skipped.

Compile time filter specification

Level filter can be set at runtime, via Cargo features. This level is configured separately for release and debug builds through the following feature flags:

• max_level_off
• max_level_error
• max_level_warn
• max_level_info
• max_level_debug
• max_level_trace
• release_max_level_off
• release_max_level_error
• release_max_level_warn
• release_max_level_info
• release_max_level_debug
• release_max_level_trace

These features control the value of the const MAX_LOG_LEVEL constant. The log macros check this value before logging. By default, no levels are disabled.

For example, a crate can disable trace level logs in debug builds and trace, debug, and info level logs in release builds with the following configuration:

[dependencies]
quicklog = { version = "0.1", features = ["max_level_debug", "release_max_level_warn"] }
