pub struct DynamicServerConfig { /* private fields */ }Expand description
Atomically swappable wrapper around a [rustls::ServerConfig].
A clone costs one Arc bump. A read is lock-free. The only expensive
operation is reload_from, which re-parses cert files.
Implementations§
Source§impl DynamicServerConfig
impl DynamicServerConfig
Sourcepub fn from_tls_config(cfg: &TlsConfig) -> Result<Arc<Self>, TlsError>
pub fn from_tls_config(cfg: &TlsConfig) -> Result<Arc<Self>, TlsError>
Build a fresh DynamicServerConfig from a TlsConfig.
This function reads the cert, the key, and the optional client-CA paths immediately.
§Errors
Propagates the underlying TlsError from
TlsConfig::build_server_config.
Sourcepub fn current(&self) -> Arc<ServerConfig>
pub fn current(&self) -> Arc<ServerConfig>
Snapshot the current ServerConfig.
The returned Arc is independent of later
reload_from calls. A concurrent reload does not
change the handshakes that already run against this snapshot.
Sourcepub fn reload_from(&self, cfg: &TlsConfig) -> Result<(), TlsError>
pub fn reload_from(&self, cfg: &TlsConfig) -> Result<(), TlsError>
Re-read the cert, the key, and the optional client-CA from disk, then
swap the new ServerConfig in atomically.
On error this function keeps the previous config in place and returns the error to the caller.
A reload has no semantic effect when the inputs have not changed. But
rustls exposes no content-equality hash on ServerConfig, so this
function rebuilds unconditionally. A caller that wants to skip identical
reloads should diff the mtimes upstream.
§Errors
Propagates the underlying TlsError from
TlsConfig::build_server_config.

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().

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().

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.

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);
