Struct HeaderView 

pub struct HeaderView<'a> { /* private fields */ }

A minimal, borrowed view of request headers.

Backed by the transport’s parsed headers; the SPI may read a header (e.g. to find a partition key) but cannot mutate it here, mutations are expressed as crate::HeaderOps in the returned decision.

Examples

use osproxy_spi::HeaderView;
let raw = vec![("X-Tenant".to_owned(), "acme".to_owned())];
let view = HeaderView::new(&raw);
assert_eq!(view.get("x-tenant"), Some("acme")); // case-insensitive
assert_eq!(view.get("absent"), None);

Implementations

impl<'a> HeaderView<'a>

pub fn new(headers: &'a [(String, String)]) -> Self

Wraps a parsed header list.

pub fn get(&self, name: &str) -> Option<&'a str>

Returns the first value for name (ASCII-case-insensitive), if present.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Copy for HeaderView<'a>

impl<'a> Debug for HeaderView<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result
