Module http 

The transport seam between providers and the network.

Providers build HttpRequests and map HttpResponses; they never own a client. The engine supplies the HttpClient, which is where per-request pacing, timeouts and the user agent live, so every provider gets the same politeness for free. Tests supply a client that replays recorded fixtures.

A client returns Ok for any HTTP response, whatever the status; only transport failures (connection, TLS, timeout) are Err. Mapping statuses to Errors is provider knowledge.

Functions

escape_lucene

Escapes Lucene/Solr query syntax in user text (DataCite, Open Library), so “BERT: Pre-training” is searched as words, not parsed as a field query.

path_segment

Escapes an identifier for use in a URL path, leaving / and : literal: APIs expect /works/doi:10.1038/nature14539 as written, but DOIs may contain #, ? or <>, which must not be taken as URL syntax.
