Struct ConfigTable 

pub struct ConfigTable {
    pub profiler_config: ProfilerConfig,
    pub sources_config: HashMap<String, Value>,
    /* private fields */
}

The structure used to resolve sources from toml configuration and the profiler config.

Fields

profiler_config: ProfilerConfig

Global Joule Profiler configuration.

sources_config: HashMap<String, Value>

Raw TOML values for each named metric source, keyed by source ID.

Implementations

impl ConfigTable

pub fn new(global_config: GlobalConfig, sources: &[Source]) -> Self

Creates a new ConfigTable from a GlobalConfig and the sources enabled from the CLI.

The enabled_sources set is the union of:

• sources declared in the global config file, and
• sources passed directly via the sources CLI argument.

pub fn apply_cli(&mut self, cli: &mut CliArgs)

Applies every CLI override of the global (profiler-level) configuration in one pass, so ConfigTable::to_config can read profiler_config directly afterwards instead of re-merging cli itself.

Only the flags that have no configuration key of their own go through here: the -D overrides are already merged into the configuration before the table is built.

pub fn build_source<R>(&mut self) -> Result<Option<R>>

where R: MetricReader,

Builds a metric source reader using the provided configuration into the config table, or default configuration if not configured.

It returns an error if the source initialization fails and ignore_on_failure is not set.

pub fn build_source_override<R>( &mut self, config_override_fn: impl FnOnce(&mut R::Config), ) -> Result<Option<R>>

where R: MetricReader,

Builds a metric source reader, applying an external config override through a caller-supplied closure before construction.

It returns an error if the source initialization fails and ignore_on_failure is not set.

impl ConfigTable

pub fn ensure_sources_are_known(&self) -> Result<()>

Errors on the configured sources no registered source claimed.

Must be called once every source has been registered: build_source takes its own section out of the table, so what is left can only be misspelled source names.

pub fn to_config(self, cli: CliArgs) -> Result<Config>

Consumes the ConfigTable and a final CliArgs to produce the core Config.

Returns an error if the configuration is invalid.

Trait Implementations

impl Debug for ConfigTable

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

Formats the value using the given formatter.
