HttpRangeSource

qualia_core_db::q42::q42_volume

Struct HttpRangeSource 

Source 
pub struct HttpRangeSource { /* private fields */ }
Expand description

Native HTTP byte-range source for trusted gateways. It never accepts a 200 OK full-body fallback: large Q42 access must stay range-bounded.

Implementations§

Source§

impl HttpRangeSource

Source

pub fn new(url: &str, length: u64) -> Result<Self>

Source

pub fn discover(url: &str) -> Result<Self>

Discover an immutable source length without downloading its body. This is a cold construction operation used for a root URL (including IPNS). Gateways that omit Content-Length on HEAD must still prove a one-byte 206 range response before they are accepted.
