Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

debug: Option<bool>

If true, enables debugging of HTTP requests. The debug information can be seen by setting the CARGO_LOG=network=debug environment variable (or use network=trace for even more information).

Cargo Reference

proxy: Option<String>

Sets an HTTP and HTTPS proxy to use. The format is in libcurl format as in [protocol://]host[:port]. If not set, Cargo will also check the http.proxy setting in your global git configuration. If none of those are set, the HTTPS_PROXY or https_proxy environment variables set the proxy for HTTPS requests, and http_proxy sets it for HTTP requests.

Cargo Reference

timeout: Option<u32>

Sets the timeout for each HTTP request, in seconds.

Cargo Reference

cainfo: Option<String>

Path to a Certificate Authority (CA) bundle file, used to verify TLS certificates. If not specified, Cargo attempts to use the system certificates.

Cargo Reference

check_revoke: Option<bool>

This determines whether or not TLS certificate revocation checks should be performed. This only works on Windows.

Cargo Reference

low_speed_limit: Option<u32>

This setting controls timeout behavior for slow connections. If the average transfer speed in bytes per second is below the given value for http.timeout seconds (default 30 seconds), then the connection is considered too slow and Cargo will abort and retry.

Cargo Reference

multiplexing: Option<bool>

When true, Cargo will attempt to use the HTTP2 protocol with multiplexing. This allows multiple requests to use the same connection, usually improving performance when fetching multiple files. If false, Cargo will use HTTP 1.1 without pipelining.

Cargo Reference

user_agent: Option<String>

Specifies a custom user-agent header to use. The default if not specified is a string that includes Cargo’s version.
