pub struct Limits { /* fields omitted */ }Mapping from data type to size limits.
A Limits structure contains a mapping from a given data type ("forms",
"json", and so on) to the maximum size in bytes that should be accepted by a
Rocket application for that data type. For instance, if the limit for
"forms" is set to 256, only 256 bytes from an incoming form request will
be read.
As documented in the config module, the default limits
are as follows:
A Limits structure is created following the builder pattern:
use rocket::config::Limits;
let limits = Limits::new()
.limit("forms", 64 * 1024)
.limit("json", 3 * 1024 * 1024);
Construct a new Limits structure with the default limits set.
use rocket::config::Limits;
let limits = Limits::new();
assert_eq!(limits.get("forms"), Some(32 * 1024));
Adds or replaces a limit in self, consuming self and returning a new
Limits structure with the added or replaced limit.
use rocket::config::Limits;
let limits = Limits::new()
.limit("json", 1 * 1024 * 1024);
assert_eq!(limits.get("forms"), Some(32 * 1024));
assert_eq!(limits.get("json"), Some(1 * 1024 * 1024));
let new_limits = limits.limit("json", 64 * 1024 * 1024);
assert_eq!(new_limits.get("json"), Some(64 * 1024 * 1024));
Retrieve the set limit, if any, for the data type with name name.
use rocket::config::Limits;
let limits = Limits::new()
.limit("json", 64 * 1024 * 1024);
assert_eq!(limits.get("forms"), Some(32 * 1024));
assert_eq!(limits.get("json"), Some(64 * 1024 * 1024));
assert!(limits.get("msgpack").is_none());
