Struct trillium_static::StaticFileHandler

impl StaticFileHandler

pub fn new(fs_root: impl AsRef<Path>) -> Self

builds a new StaticFileHandler

If the fs_root is a file instead of a directory, that file will be served at all paths.

use trillium_static::{StaticFileHandler, crate_relative_path};
let mut handler = StaticFileHandler::new(crate_relative_path!("examples/files"));

use trillium_testing::prelude::*;
init(&mut handler);

assert_not_handled!(get("/").on(&handler)); // no index file configured

assert_ok!(
    get("/index.html").on(&handler),
    "<h1>hello world</h1>",
    "content-type" => "text/html; charset=utf-8"
);

pub fn without_etag_header(self) -> Self

do not set an etag header

pub fn without_modified_header(self) -> Self

do not set last-modified header

pub fn with_index_file(self, file: &str) -> Self

sets the index file on this StaticFileHandler


use trillium_static::{StaticFileHandler, crate_relative_path};

let handler = StaticFileHandler::new(crate_relative_path!("examples/files"))
    .with_index_file("index.html");

use trillium_testing::prelude::*;
assert_ok!(get("/").on(&handler), "<h1>hello world</h1>", "content-type" => "text/html; charset=utf-8");

Trait Implementations§

impl Debug for StaticFileHandler

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

Formats the value using the given formatter. Read more

impl Handler for StaticFileHandler

fn init<'life0, 'life1, 'async_trait>( &'life0 mut self, _info: &'life1 mut Info ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Performs one-time async set up on a mutable borrow of the Handler before the server starts accepting requests. This allows a Handler to be defined in synchronous code but perform async setup such as establishing a database connection or fetching some state from an external source. This is optional, and chances are high that you do not need this. Read more

fn run<'life0, 'async_trait>( &'life0 self, conn: Conn ) -> Pin<Box<dyn Future<Output = Conn> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Executes this handler, performing any modifications to the Conn that are desired.

fn before_send<'life0, 'async_trait>( &'life0 self, conn: Conn ) -> Pin<Box<dyn Future<Output = Conn> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: 'async_trait,

Performs any final modifications to this conn after all handlers have been run. Although this is a slight deviation from the simple conn->conn->conn chain represented by most Handlers, it provides an easy way for libraries to effectively inject a second handler into a response chain. This is useful for loggers that need to record information both before and after other handlers have run, as well as database transaction handlers and similar library code. Read more

fn has_upgrade(&self, _upgrade: &Upgrade<BoxedTransport>) -> bool

predicate function answering the question of whether this Handler would like to take ownership of the negotiated Upgrade. If this returns true, you must implement [Handler::upgrade]. The first handler that responds true to this will receive ownership of the [trillium::Upgrade][crate::Upgrade] in a subsequent call to [Handler::upgrade]

fn upgrade<'life0, 'async_trait>( &'life0 self, _upgrade: Upgrade<BoxedTransport> ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: 'async_trait,

This will only be called if the handler reponds true to [Handler::has_upgrade] and will only be called once for this upgrade. There is no return value, and this function takes exclusive ownership of the underlying transport once this is called. You can downcast the transport to whatever the source transport type is and perform any non-http protocol communication that has been negotiated. You probably don’t want this unless you’re implementing something like websockets. Please note that for many transports such as TcpStreams, dropping the transport (and therefore the Upgrade) will hang up / disconnect.
