Struct bdrck::logging::LogFilters

pub struct LogFilters(pub Vec<LogFilter>);

LogFilters is a structure which defines the full set of filters a Logger should apply to log messages before actually outputting them.

Tuple Fields

0: Vec<LogFilter>

Implementations

impl LogFilters

pub fn max_level_for(&self, module_path: &str) -> LevelFilter

Returns the LevelFilter which should be applied to the given module. If no LogFilter entries apply to the given module, Trace is returned instead, since logging messages are enabled by default in this library. If multiple LevelFilters matched the given module, then the lowest (i.e., most restrictive) LevelFilter is returned.

Trait Implementations

impl FromStr for LogFilters

fn from_str(s: &str) -> Result<LogFilters>

Parse a set of log filters from a string.

We assume that the regex contained in log filters will only contain certain characters: those which can appear in valid module names (something like [A-Za-z_][A-Za-z0-9_]* separated by :’s), and maybe some modifiers or etc., like *+?|(){}[].

But, we want a string to contain several filters. So, using the above assumption about what characters will appear in the regex, we’ll use the ; character as a separator. So, the final format is:

regex=level;regex=level;…

type Err = Error

The associated error which can be returned from parsing.
