LinkHeader

Struct LinkHeader 

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

Builder for constructing RFC 8288 Link headers.

Supports multiple links in a single header value, pagination helpers, and custom relation types.

§Example

use fastapi_core::{LinkHeader, LinkRel};

let header = LinkHeader::new()
    .link("https://api.example.com/users?page=2", LinkRel::Next)
    .link("https://api.example.com/users?page=1", LinkRel::Prev)
    .link("https://api.example.com/users?page=1", LinkRel::First)
    .link("https://api.example.com/users?page=5", LinkRel::Last);

assert!(header.to_string().contains("rel=\"next\""));

Implementations§

Source§

impl LinkHeader

Source

pub fn new() -> Self

Create an empty link header builder.

Add a link with the given URL and relation.

Source

pub fn add(self, link: Link) -> Self

Add a fully configured Link entry.

Source

pub fn paginate( self, base_url: &str, page: u64, per_page: u64, total: u64, ) -> Self

Add pagination links from page/per_page/total parameters.

Generates first, last, next, prev, and self links using the given base URL and query parameters.

Source

pub fn is_empty(&self) -> bool

Returns true if no links have been added.

Source

pub fn len(&self) -> usize

Returns the number of links.

Source

pub fn to_header_value(&self) -> String

Source

pub fn apply(self, response: Response) -> Response

Apply this Link header to a response.
