Struct EspIdfLogFilter 

pub struct EspIdfLogFilter { /* private fields */ }

Log filter backend based on the ESP-IDF logging configuration.

This filter is useful when the user would like to control the verbosity of the logging system based on the ESP-IDF configuration settings, which should apply both to the ESP-IDF native C logging, as well as to logging from Rust.

This backend uses the ESP-IDF logging system to filter log messages based on their target and level. Specifically:

• The log crate is set to max level equal to the CONFIG_LOG_MAXIMUM_LEVEL ESP-IDF configuration.
• The set_target_level method allows setting the log level for specific log targets (both targets based on Rust logging - i.e. most often than not Rust modules, as well as native ESP-IDF targets).

Implementations

impl EspIdfLogFilter

pub const fn new() -> Self

Create a new instance of EspIdfLogFilter.

pub fn initialize(&self)

Initialize the ESP-IDF log filter backend.

pub fn get_max_level(&self) -> LevelFilter

Return the maximum log level configured in the ESP-IDF.

pub fn set_target_level( &self, target: impl AsRef<str>, level_filter: LevelFilter, ) -> Result<(), EspError>

Set the log level for a specific target.

Arguments:

• target: The target for which to set the log level. This can be a Rust log target, or an ESP-IDF native target.
• level_filter: The log level to set for the target.

pub fn enabled(&self, metadata: &Metadata<'_>) -> bool

Check if logging for the given metadata is enabled, based on the ESP-IDF current log level, including taeget-specific log levels.
