Struct Config 

pub struct Config {
    pub preset: Preset,
    pub toolsets: BTreeSet<Toolset>,
    pub max_tier: Tier,
    pub disabled: BTreeSet<Surface>,
    pub cli_path: Option<PathBuf>,
    pub max_result_bytes: usize,
    pub api_base_url: String,
    pub tailnet: String,
    pub log_filter: String,
    pub http: Option<HttpConfig>,
}

The configuration the server actually runs with.

Fields

preset: Preset

The preset the selection started from, kept for diagnostics.

toolsets: BTreeSet<Toolset>

The toolsets to offer, after any adjustment.

max_tier: Tier

The most dangerous tier permitted.

disabled: BTreeSet<Surface>

Surfaces the operator switched off. A surface can also be unavailable because its backend is missing, which is decided at startup, not here.

cli_path: Option<PathBuf>

max_result_bytes: usize

api_base_url: String

Where the control-plane calls go. The real control plane unless a test or a staging environment says otherwise; validated when the client is built, because that is where the rule about what is safe lives.

tailnet: String

The tailnet a control-plane path means when the caller does not name one.

log_filter: String

http: Option<HttpConfig>

Serve over HTTP instead of stdio, when the operator asked for it.

Implementations

impl Config

pub fn resolve(cli: Cli) -> Result<Self, ConfigError>

Resolve the command line against the process environment.

pub fn resolve_with( cli: Cli, source: impl Fn(&str) -> Option<String>, ) -> Result<Self, ConfigError>

Resolve the command line against an arbitrary source of variables.

pub fn is_disabled(&self, surface: Surface) -> bool

Whether the operator switched this surface off.

pub fn changed_settings(&self) -> Vec<(&'static str, String)>

The settings that differ from what this server would do on its own, as the variables that would reproduce them.

This is resolve run backwards, which is why it lives beside it: every field it reads and every variable it names is this module’s, and a setting added to one without the other is a snippet that does not reproduce the server it was printed from.

Only what the operator changed. A snippet spelling out every default would be a snippet nobody reads, and every value in it would go stale the day a default changed.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.
