pub struct AddressPoolManager { /* private fields */ }Expand description
Manages IP address allocation across a global pool and optional per-user reserved pools.
Users with a per-user pool get addresses exclusively from their reserved set. Users without a per-user pool get addresses from the global (unreserved) pool. Reserved addresses are pre-inserted into the global pool’s used set at construction time so they are never handed out to unrestricted users.
Implementations§
Source§impl AddressPoolManager
impl AddressPoolManager
Sourcepub fn new(
network: IpNet,
user_pools: HashMap<String, Vec<AddressRange>>,
) -> Result<Self>
pub fn new( network: IpNet, user_pools: HashMap<String, Vec<AddressRange>>, ) -> Result<Self>
Creates a new address pool manager for the given tunnel network.
The global pool covers the entire tunnel network with the network address, server address, and broadcast address pre-reserved. All addresses from per-user pools are also pre-reserved in the global pool.
§Performance
Every address in every per-user range is iterated eagerly for validation
and reservation. Very large ranges (e.g. a /8 with ~16 M addresses)
will cause proportional memory and CPU usage at startup. Prefer narrow
per-user ranges (a /24 or smaller is typical).
§Arguments
network- the tunnel network (server IP + netmask)user_pools- per-user address ranges, keyed by username
§Errors
Returns AuthError::InvalidUserStore if any user pool address falls
outside the tunnel network or is a reserved tunnel address (network,
server, or broadcast).
Sourcepub fn allocate_address(&self, username: &str) -> Option<IpNet>
pub fn allocate_address(&self, username: &str) -> Option<IpNet>
Sourcepub fn release_address(&self, username: &str, address: &IpAddr)
pub fn release_address(&self, username: &str, address: &IpAddr)
Releases an address back to the appropriate pool.
If the user has a per-user pool, releases to that pool. Otherwise releases to the global pool.
§Arguments
username- the authenticated usernameaddress- the address to release

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().
use yansi::Paint;
painted.on_red();Source§fn on_primary(&self) -> Painted<&T>

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
