pub struct TypedConfigOps {
pub schema: Value,
/* private fields */
}Expand description
Type-erased view onto a wired typed config.
Carries the JSON Schema for C and a closure that renders the
merged C value as a serde_json::Value. Constructed via
TypedConfigOps::new at builder time when C is still in
scope.
Stored on crate::app::App as Option<Arc<TypedConfigOps>>
— Some when the host tool called
Application::builder().config(c), None for the v0.4-style
raw-YAML fallback path.
Fields§
§schema: ValueJSON Schema for C, generated via
schemars::SchemaGenerator::root_schema_for::<C>() and
serialised to a serde_json::Value.
Implementations§
Source§impl TypedConfigOps
impl TypedConfigOps
Sourcepub fn new<C>() -> Self
pub fn new<C>() -> Self
Build the ops bundle for C. Captures C in the
render_value closure; the resulting struct is dyn-stable
and Send + Sync.
Sourcepub fn render(&self, erased: &ErasedConfig) -> Option<Value>
pub fn render(&self, erased: &ErasedConfig) -> Option<Value>
Render the merged value backing erased as a
serde_json::Value. Returns None if erased does not
contain a Config<C> of the type captured at construction
time — in practice this should only happen when the same
App is constructed with mismatched ops + erased-config
pairings, which the public surface prevents.

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().

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().

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().

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);
