PacDirectives

rama::js::pac

Struct PacDirectives 

pub struct PacDirectives(/* private fields */);
Available on crate features js and pac and std only.
Expand description

The ordered proxy list a PAC script returned: try each in turn, falling back to the next when one is unreachable.

Implementations§

§

impl PacDirectives

pub const MAX_PARSED_TOKENS: usize = 64

How many ;-separated tokens of a script result are read at all.

A parse of a multi-megabyte result must not allocate a directive per token, so the tail beyond this is not even looked at.

pub fn new(directives: impl IntoIterator<Item = PacDirective>) -> PacDirectives

The given directives, in the order they should be tried.

pub fn direct() -> PacDirectives

A list that only goes PacDirective::Direct.

pub fn as_slice(&self) -> &[PacDirective]

The directives, in the order the script returned them.

pub fn is_empty(&self) -> bool

Returns true if the script returned nothing usable.

pub fn len(&self) -> usize

The number of directives.

pub fn first(&self) -> Option<&PacDirective>

The first directive, if any.

pub fn truncate(&mut self, max: usize) -> usize

Keep the first max directives, dropping the rest, and return how many were dropped.

A script decides how many proxies a single request may be dialled against, so whoever acts on a verdict bounds it.

pub fn into_proxy_routes(self) -> ProxyRoutes

The ordered ProxyRoutes this list selects, ready to hand to a ProxyRoutesConnector.

pub fn proxy_addresses(&self) -> impl Iterator<Item = ProxyAddress>

Iterate the proxies to try, skipping PacDirective::Direct.

impl FromStr for PacDirectives

§
