Struct FeedHttpClient 

pub struct FeedHttpClient { /* private fields */ }

HTTP client for fetching feeds

Implementations

impl FeedHttpClient

pub fn new() -> Result<Self>

Creates a new HTTP client with default settings

Default settings:

• 30 second timeout
• Gzip, deflate, and brotli compression enabled
• Maximum 10 redirects, each re-validated against the SSRF checks
• DNS resolution re-validated against the SSRF checks to close DNS-rebinding gaps between validation and connect time
• No system/environment proxy (HTTP_PROXY, HTTPS_PROXY, ALL_PROXY) is honored: a proxy connects through a hostname that is resolved by the proxy itself, not by the DNS-rebinding-safe resolver above, which would silently defeat that protection
• Custom User-Agent

Errors

Returns FeedError::Http if the underlying HTTP client cannot be created.

pub fn with_user_agent(self, agent: String) -> Self

Sets a custom User-Agent header

Security

User-Agent is truncated to 512 bytes to prevent header injection attacks.

pub const fn with_timeout(self, timeout: Duration) -> Self

Sets the per-request timeout applied to every Self::get call.

The value is a total deadline covering connection, all redirect hops, and the full response body — not a per-hop timeout. Duration::ZERO means “time out immediately”, not “disable the timeout”; this API has no way to disable it entirely. Values above one hour are clamped to one hour: reqwest’s blocking wait computes its deadline as Instant::now() + timeout without an overflow check, so passing Duration::MAX (or another value near the Instant range limit) would otherwise panic instead of erroring.

pub fn get( &self, url: &str, etag: Option<&str>, modified: Option<&str>, extra_headers: Option<&HeaderMap>, ) -> Result<FeedHttpResponse>

Fetches a feed from the given URL

Supports conditional GET with ETag and Last-Modified headers.

Arguments

• url - HTTP/HTTPS URL to fetch
• etag - Optional ETag from previous fetch
• modified - Optional Last-Modified from previous fetch
• extra_headers - Additional custom headers

Errors

Returns FeedError::Http if the request fails or headers are invalid.
