Struct RateLimits 

#[non_exhaustive]
pub struct RateLimits { /* private fields */ }

Process-wide rate limits. Hard-coded; not configurable.

Construct only via RateLimits::HARD_CODED. The struct fields are pub(crate) so downstream code cannot synthesize a RateLimits with different values, which would weaken docs/LEGAL.md §6 safeguard 8.

Implementations

impl RateLimits

pub const HARD_CODED: Self

The single, hard-coded set of rate limits. There is no other public constructor — see the type-level docs.

pub const fn max_concurrent_fetches(&self) -> u32

Maximum number of concurrent fetches in flight.

pub const fn max_fetches_per_second(&self) -> f32

Maximum fetch attempts per second across all sources.

pub const fn per_source_backoff_ms(&self) -> u64

Per-source backoff in milliseconds between consecutive requests.

The floor that applies to every source. A source whose vendor publishes something stricter gets that instead – see Self::backoff_ms_for.

pub fn backoff_ms_for(&self, source: &str) -> u64

The minimum gap between two requests to source, in milliseconds.

Self::per_source_backoff_ms unless SOURCE_RATE_OVERRIDES names a stricter value, in which case the stricter one wins. Never looser: docs/SOURCES.md promises doiget adopts a stricter vendor guideline at the per-source level rather than relaxing the global cap, and max here is what makes that promise structural instead of a matter of getting every table entry right.

pub fn max_concurrent_for(&self, source: &str) -> u32

The concurrency ceiling for source.

Clamped to Self::max_concurrent_fetches, so a table entry can only ever tighten the global cap.
