Struct BackendSection 

pub struct BackendSection {
    pub base_url: String,
    pub auth: AuthConfig,
    pub http: HttpConfig,
}

[backend] section — the OpenAPI/REST HTTP backend declaration (D-06).

This is the HTTP analog of DatabaseSection: it identifies the upstream REST API the synthesized tools call. base_url is the API root; the optional [backend.auth] sub-table selects an AuthConfig variant (type = "...") and [backend.http] carries HttpConfig tuning (timeout / retries / …).

Gated behind the http feature — the whole section (and the ServerConfig::backend field) is absent in a no-http build so there is no dead stub type. AuthConfig and HttpConfig are DEFINED in crate::http (Plan 90-01) and re-exported here, not redefined (H3).

Strict-parse discipline (D-13) is preserved: #[serde(deny_unknown_fields)] rejects a typo’d key under [backend] or [backend.http].

Secrets posture (T-90-02-02): inline token fields under [backend.auth] hold operator references (${ENV} / env:VAR) resolved upstream by the Phase 83 secrets machinery — config parsing stores the string verbatim and never the resolved value.

Fields

base_url: String

REST API root URL (e.g. "https://api.tfl.gov.uk"). Single-call tools concatenate their path onto this (an empty per-tool base_url inherits this value).

auth: AuthConfig

[backend.auth] — outgoing authentication (AuthConfig, six modes). Defaults to AuthConfig::None when the sub-table is omitted.

http: HttpConfig

[backend.http] — client tuning (HttpConfig: timeout / retries / backoff / user-agent / default headers). Defaults to HttpConfig’s defaults when the sub-table is omitted.

Trait Implementations

impl Clone for BackendSection

fn clone(&self) -> BackendSection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendSection

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

Formats the value using the given formatter.

impl Default for BackendSection

fn default() -> BackendSection

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BackendSection

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BackendSection

fn eq(&self, other: &BackendSection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BackendSection

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
