Struct HostPattern 

pub struct HostPattern(/* private fields */);

A compiled pattern for matching a Host.

The representation is intentionally private. Construct patterns explicitly with exact, sub, or try_glob, or parse conventional syntax through try_new.

use rama_net::address::{Domain, Host, HostPattern};

let pattern = HostPattern::sub(Domain::from_static("example.com"));
assert!(pattern.matches(Host::from_static("api.example.com").view()));
assert!(!pattern.matches(Host::LOCALHOST_IPV4.view()));

Implementations

impl HostPattern

pub const fn exact(host: Host) -> Self

Match exactly one host.

This constructor performs no parsing.

pub fn sub(domain: Domain) -> Self

Match a domain and all of its descendants.

This constructor performs no parsing.

pub fn try_glob(pattern: impl Into<Cow<'static, str>>) -> Result<Self, BoxError>

Compile a flat case-insensitive host glob.

* matches any sequence of bytes, including dots. Matching is ASCII case-insensitive against HostRef::to_str, so a glob can match domain names and IP literals alike. A static string is borrowed by the compiled wildcard; an owned String transfers its allocation.

pub fn try_new(pattern: impl TryIntoHostPattern) -> Result<Self, BoxError>

Parse a host pattern.

Plain hosts are exact, .example.com and *.example.com are domain subtree patterns, and other values containing * are flat host globs.

pub fn matches(&self, host: HostRef<'_>) -> bool

Return whether this pattern matches host.
