Struct LogLevelController 

pub struct LogLevelController { /* private fields */ }

Controller for dynamic log level management.

This struct provides methods to change log levels at runtime. It wraps a reload::Handle from tracing-subscriber.

Implementations

impl LogLevelController

pub fn new( handle: Handle<EnvFilter, Registry>, initial_level: LogLevel, ) -> LogLevelController

Create a new log level controller with the given reload handle.

pub fn register_global(self) -> bool

Register this controller as the global instance.

Returns true if registration succeeded, false if a controller was already registered.

pub fn global() -> Option<&'static LogLevelController>

Get the global log level controller, if one is registered.

pub fn current_level(&self) -> LogLevel

Get the current global log level.

pub fn module_levels(&self) -> HashMap<String, LogLevel>

Get all current module-specific log levels.

pub fn set_level(&self, level: LogLevel) -> Result<(), Error>

Set the global log level.

This immediately affects all log output that doesn’t have a module-specific override.

pub fn set_module_level( &self, module: impl Into<String>, level: LogLevel, ) -> Result<(), Error>

Set the log level for a specific module.

Arguments

• module - The module path (e.g., “mabi_core::engine”)
• level - The log level to set

pub fn remove_module_level(&self, module: &str) -> Result<(), Error>

Remove a module-specific log level override.

pub fn clear_module_levels(&self) -> Result<(), Error>

Clear all module-specific log level overrides.

pub fn enable_debug_mode(&self) -> Result<DebugModeGuard, Error>

Temporarily increase verbosity for debugging.

This is a convenience method that sets the global level to Debug and can be easily reverted.

pub fn enable_module_trace( &self, module: impl Into<String>, ) -> Result<ModuleTraceGuard, Error>

Temporarily increase verbosity for a specific module.

pub fn current_filter_string(&self) -> String

Get the current filter string (for debugging purposes).

Trait Implementations

impl Clone for LogLevelController

fn clone(&self) -> LogLevelController

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

Performs copy-assignment from source.

impl Debug for LogLevelController

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